The goal of this thesis is to provide information on how the music distribution has evolved throughout the years since the internet and computers have brought a
new digital ear to the music industry. This gave unlimited access to vast amount of information, creating new methods of communication and connecting to thousands of music lovers with only one mouse click. Technological and social changes have
followed ever since the beginning of the 20th century with significant impact on different business aspects like Marketing, Communication and Pricing. In the following years illegal downloading has brought the music industry to a crash with sales dropping
almost double in only one year. This, however, led to the idea of legal downloading and later in 2008 to the birth of the most used music streaming service Spotify. The bundle paying method of this new service has not only put the industry back on its feet
but it has also brought the interest in the consumers back. A monthly “flat rate” in exchange of a vast music catalogue of more than 30,000 songs, albums and artists with the ability to listen to it offline turned out to be the better alternative.
The purpose of this paper is to conduct an explorative research on the current situation of the music business and the business models of the new trend “music streaming” by using different analytical methods. The research results show a significant change in the way Marketing and Communication are being done by labels, brands and the streaming services due to the rapid technological progress and the new social habits born with it. Using the experience of listening to music, data and audience intelligence provided by the services, brands are now able to communicate their exact message in front of the right person and in the right time. Pricing of music has also gone through a big transition
since music streaming has become the preferred way of listening to and exploring new music. The effect of the bundles provides users with unlimited usage of the music streaming service and its catalogue in exchange of a monthly fee also called “flat rate”.
Each service decides on the price and the subscription method to be offered. To give a more comprehensive picture on what the future of music streaming
is, this paper is using not only secondary data but primary data as well. In order to generate free discussion, the study refers to the media and an expert to give answer on what are the signs pointing the direction the music business is headed towards.
Die vorliegende Arbeit hat das Ziel, den Best Practice Austausch im Marketing durch eine dialog-optimierte Plattform zu verbessern. Dazu wurde die definierte Plattform umstrukturiert, um eine gezieltere Nutzung gewährleisten zu können. Außerdem wurde eine Handlungsempfehlung zur Förderung des Austauschs auf lange Sicht abgegeben.
Im theoretischen Abschnitt der Arbeit wurde die Verbindung von Wissensmanagement und Best Practice beleuchtet und ihre Auswirkung auf die Wettbewerbsfähigkeit eines Unternehmens illustriert. Darüber hinaus wurde die Rolle der internen Kommunikation in einer allgemeinen Community of Practices thematisiert. Daraufhin wurden die Funktionen von Web 2.0 erläutert, die in Unternehmen den Austausch von Informationen, Erfahrungen und Wissen unterstützen.
Zur Ermittlung des aktuellen Ist-Zustands von Best Practice Austausch auf einer Plattform, wurden im praktischen Abschnitt dieser Arbeit drei qualitative explorative empirische Forschungsmethoden angewendet: Datenanalyse anhand eines Reportings der aktuell genutzten Plattform, Experteninterview mit Mitarbeitern vom Marketing (aus der Zentrale und international) sowie der technischen Abteilung Business Process und eine Fallstudienanalyse über Austausch auf einer internen Plattform. Die Umstrukturierung und die Handlungsempfehlung basieren auf diesen gewonnenen Daten.
Schlussfolgernd kann behauptet werden, dass eine Plattform den Best Practice Austausch nur unterstützen und nicht antreiben kann, wenn die interne Kommunikationskultur den Austausch und die Zusammenarbeit nicht fördert. Außerdem spielt Wissensmanagement dabei eine wichtige Rolle, damit Mitarbeiter die festgelegte Plattform effizient nutzen können. Anreiz und Belohnungssysteme zum Austausch vervollständigen diese Maßnahmen.
Cameras play a prominent role in the context of 3D data, as they can be designed to be very cheap and small and can therefore be used in many 3D reconstruction systems. Typical cameras capture video at 20 to 60 frames per second, resulting in a high number of frames to select from for 3D reconstruction. Many frames are unsuited for reconstruction as they suffer from motion blur or show too little variation compared to other frames. The camera used within this work has built-in inertial sensors. What if one could use the built-in inertial sensors to select a set of key frames well-suited for 3D reconstruction, free from motion blur and redundancy, in real time? A random forest classifier (RF) is trained by inertial data to determine frames without motion blur and to reduce redundancy. Frames are analyzed by the fast Fourier transformation and Lucas–Kanade method to detect motion blur and moving features in frames to label those correctly to train the RF. We achieve a classifier that omits successfully redundant frames and preserves frames with the required quality but exhibits an unsatisfied performance with respect to ideal frames. A 3D reconstruction by Meshroom shows a better result with selected key frames by the classifier. By extracting frames from video, one can comfortably scan objects and scenes without taking single pictures. Our proposed method automatically extracts the best frames in real time without using complex image-processing algorithms.
Mergers and Acquisitions are powerful tools for companies worldwide and it has been implemented since many years. However, in a time of globalisation M&A is even more important than ever. There are several reasons for companies to perform Mergers and Acquisitions, such as strategically, political or to prevent bankruptcy (Rosenbaum & Pearl, 2013). However, M&A’s are more often a failure than successes, due to the wrong reasons of a Merger and Acquisition or because of the wrong implementation of such (Bloomberg, 2013).
This study aims to give an insight of how to implement a Merger and Acquisition and what is important to be successful. Therefore, a comparative equation between the cases of Daimler and Chrysler and Exxon and Mobil is conducted to get real life data about a very successful case, here Exxon/Mobil and a very unsuccessful case, here Daimler/Chrysler. These results will show which tools companies should care more and less about, to implement a successful Merger and Acquisition.
Thus, the study will define what a Merger and Acquisition is and how to implement such. Furthermore, it will be carved out how to define a success or failure, which is very critical to the outcome of an evaluation. After the equation of the two cases the question will be dissolved if there is a clear answer on a strict path to follow for a successful merger or acquisition, or is there no formula for a successful M&A.
The video game industry has come a long way from its humble beginnings in a computer lab at the Brookhaven National Laboratory’s instrumentation group to a multi billion-dollar industry. Considering that the gaming industry is a relatively young industry, it has faced a substantial amount of structural changes and shifts that were intensified by mega trends (i.e. Digitalization) that influence every industry in a certain way. One of these structural changes was the emergence of smaller studios, also known as “indie studios”. Even though these studios have always been a part of the industry, they themselves and their games respectively have gained a lot of appreciation and support over the last decade. Some of these titles even managed to upset those of the big and established studios, also referred to as AAA studios. The most dominant factors that allowed for the emergence and the success of smaller studios were the drastically reduced entry barriers (i.e. free development kits, online distribution websites) and the supportive environment offered to them (e.g. university programs, incubators). Yet, some studios manage to generate better results with their games than other studios do and therefore remained capable of competing in the industry. This circumstance inspired this thesis to identify the KSFs (i.e. Key Success Factors), also referred to as CSFs (i.e. Critical Success Factors) that allow for a successful launch of the game. Generally speaking, KSFs are those business areas and activities that, if executed in a proper way, enable a company to compete successfully in a given market. Since their introduction in 1961 by D. Ronald Daniel, a consultant with McKinsey & Company, the KSFs have been the subject of many studies and academic research papers. A majority of the research tends to focus on applying the KSF methods to more established industries (i.e. healthcare, construction). In addition to that most of the research conducted within the field of KSFs tends to gravitate around identifying and forecasting the KSFs that might be of interest for a given time period instead of focusing on a dedicated event such as the launch of a product. This thesis therefore provides the first comprehensive research on the KSFs in the context of the gaming industry, with special regard to the smaller studios (i.e. indie studios) and the launch period of a game.
First and foremost, this study aims to identify the KSFs that are of great importance to the successful launch of a given game. Furthermore, it tries to research how these KSFs are identified and implemented by the studios. Additionally, it will be researched if the studios are using the traditional model outlined by Howell, M. (2010) or if they rely on other methodologies to identify and implement the relevant KSFs for a successful launch. Lastly, it will be analysed, how smaller (i.e. indie studios) determine whether or not a game was a success and what metrics they use for this evaluation.
The study relied on secondary data provided by scientific journals, books, conference papers from the fields of busines, project management, strategic management and gaming. Since the available scientific literature for this specific research topic was considerably scarce, a lot of the needed content and references used in this thesis were acquired through practical research.
The research followed a hybrid approach, indicating that quantitative as well as qualitative research methods were applied. The qualitative research was conducted in the form of interviews with six industry experts that all had contributed in their way to successful game launches in the past. They were thoroughly researched and evaluated before being contacted in order to ensure their ability to contribute to answering the research question. The data and inputs gathered from the qualitative research were used throughout the theoretical part of the thesis in order to compensate for the continous lack of academic resources and to support the claims made by the author. Furthermore, the data was used to create the survey (i.e. quantitative research) that would be distributed among 409 potential participants. Similar to the quantitative research, these participants were also thoroughly researched and evaluated in order to ensure the legitimacy of the results.
Findings suggest that smaller studios (i.e. indie studios) are not familiar with the traditional model proposed by Howell(2010), which tends to be employed larger corporations in rather established industries. Yet they are familiar with the concept of KSFs and determine as well as implement them through agile project management, which has its origins in the software development industry. This way studios are able to adjust and adapt their KSFs at a faster pace, which is essential due to dynamic environment they operate in. The results indicate that a majority of the participating studios use the Scrum development method in order to determine and implement the required KSFs for developing and launching their games. A significant number of studios rely on dedicated agile project management software programs that aid the companies throughout the project lifecycle. The most popular programs being Trello and Jira. The qualitative research identified a total of 22 potential KSFs that are deemed to be important for the successful launch of a game. The most crucial KSFs were considered to be the following:
- Team chemistry & intrinsic motivation & internal communication
- Budgeting & scheduling & scoping
- Selecting distribution channel & front-page promotion
- Presentation of game on websites & USP
- Active community on social networks & strong customer support & transparency
The results indicate that the traditional one dimensional metrics (i.e. sales level) of evaluating the success of a game launch might no longer have the highest weight in the opinion of studios. The success tends to be determined by a set of one-dimensional metrics, which are quantifiable (e.g. sales levels, positive reviews) and multi-dimensional metrics which are not quantifiable (e.g. learning experience, fulfilment).
Summing up, there might not be such a thing as a “magic formular” that will ensure the success of a game launch. Yet, the research aims to provide suggestions based on the findings from practical research that could be of usage to studios when launching their next game.
The presented paper analyzes share repurchase announcements of currently DAX, MDAX and SDAX listed companies during the 20-year span of 1998 to 2018. The findings show a significantly lower average abnormal return on the announcement day (1.937%) and a lower cumulative average abnormal return around the announcement day (1.943%) than previous studies reported. Moreover, the medium-term cumulative abnormal returns are found to be significant and positive (2.70%). This study finds evidence for the signaling hypothesis, which states the intention behind the repurchase of a company being a perceived undervaluation.
Keysight Technologies, a provider of electronic design and test solutions, has realized an extraordinarily successful services transformation.
In this paper, we describe the extraordinarily successful digital and service transformation journey of Keysight. Within five years, Keysight doubled its services revenues and increased the service margin by 19.5%.
Crucial for this success was the "value capture strategy" with strategic alignment, meeting customers' needs with bundled solutions of products, software, and services.
For all hardware companies, telemetry is the key to growing services profitably with digitally-enabled services and optimizing the total cost to serve.
Yet, the TSIA Field Services Benchmark data also shows that building this foundation remains difficult. The key to providing telemetry at scale is to understand and communicate the value of telemetry in two ways—internally, to get the resources to drive it, and externally to customers, to convince them to adopt and consume the telemetry offers that will drive their business outcomes.
In this paper, Harald Kopp and Kevin Bowers give guidance and key insights on how to present the value of telemetry to customers and internal stakeholders.
Mit Industrie 4.0 und dem Internet der Dinge werden Produkte intelligenter und vernetzter. Sie erzeugen mehr Daten. Diese Daten können über die Cloud allen Beteiligten zielgerichtet zur Verfügung gestellt werden, um bessere und schnellere Entscheidungen zu treffen oder Prozesse zu automatisieren und zu optimieren.
In Zukunft werden jene Unternehmen entscheidende Wettbewerbsvorteile haben, die aus diesen Daten wertvolle Informationen erzeugen, um die eigene Produktivität zu erhöhen, sich entlang der Supply Chain zu vernetzen oder Werte für Kunden zu erzeugen und damit in eine Digitale Wertschöpfung einzusteigen.
Durch die zunehmende Intelligenz der Produkte und die Möglichkeiten der Vernetzung zu einem Internet-der-Dinge entstehen zusätzliche Potenziale durch die Verarbeitung von Daten und das Angebot von datenbasierten, smarten Services. In diesem Artikel wird ein Rahmen für die Gestaltung der Digitalen Transformation für Dienstleistungen anhand des Remote Services Continuums aufgezeigt, die digitale Wertschöpfungskette beschrieben und eine Roadmap zur Erschließung dieser Potenziale dargestellt.
Onsite deployments of field personnel are highly restricted for equipment and device manufacturers as a result of the COVID-19 crisis. Oftentimes, remote support is the only way to help customers and, increasingly, customer support is provided by a virtual organization.
We now find ourselves in an environment where customers are more accepting of remote connections of their equipment and the use of cloud services to replace onsite deployments for break-fix and maintenance services. These significant shifts in the customer relationship will stay in place well beyond the crisis and are accelerating the digital transformation of vendors and customers.
In this report Prof. Harald Kopp discusses the impact of the acceleration of digital transformation for industrial equipment manufacturers.
Most industrial equipment companies have an underperforming services business and have the opportunity to grow services revenue share and the service margin simultaneously.
With this annual paper, Harald Kopp
- identifies the key trends that are impacting industrial equipment companies.
- describes the top business challenges being created by these industry trends.
- identifies the digital business shift, the new goals for digital transformation, and the digital customer experience.
For industrial equipment companies, it is a challenge to fight commoditization of products and product-attached services and to manage the digital transformation.
This report offers guidance on how to respond to the acceleration of digital transformation and XaaS transformation and discuss core capabilities that services organizations of industrial equipment manufacturers will need to embrace in order to succeed in 2021 and beyond.
Key focus areas for 2021 include:
- Strategic planning for the digital transformation.
- Creating new revenue streams, protecting the traditional ones, and increasing profitability.
- Managing the digital and XaaS transformation.
For industrial equipment companies, it is a challenge to fight commoditization of products and product-attached services, and to manage the digital transformation.
This report identifies the most relevant business challenges faced by our members. TSIA then translates the challenges into the core capabilities that services organizations of industrial equipment manufacturers will need to embrace to succeed in 2020 and beyond
E‐Collaboration and what it means for the modern business world is attracting more and more the attention of today’s leaders and professionals. Especially organizations whose products and services are interactively created and used by global teams consisting of customers and suppliers have every reason to understand E‐Collaboration for its many benefits and opportunities. This bachelor thesis investigates how E‐Collaboration can scale the information processing capacity of international sales organizations using the example of va‐Q‐tec Ltd ECollaboration tool requirements are defined taking the circumstances of va‐Q‐tec Ltd into consideration. The findings of the study show that an E‐Collaboration tool with resource management, workflow and dashboard tool features are most needed to scale va‐Q‐tec’s information processing capacity. Furthermore, this paper explores different aspects of ECollaboration including the basic components of collaboration, the incremental scaling of information processing capacity and the circumstances of today’s international sales organizations. Empirical findings reveal that scaling information processing capacity requires central storage and processor systems supported by information technology. Scaling information processing capacity by increasing the workforces is found to be inefficient. Selfservice interfaces allowing 24/7 information access and exchange are the new benchmark for sales organizations.
This thesis aims to provide a comprehensive and systematic analysis about the growing popularity of Korean pop music (K-pop) worldwide in recent years. On one hand, the international expansion of K-pop can be understood as a result of the strategic planning and business execution that are created and carried out by the entertainment agencies. On the other hand, external circumstances such as the rise of social media also create a wide array of opportunities for K-pop to broaden its global appeal. The research explores the ways how the interplay between external circumstances and organizational strategies has jointly contributed to the global circulation of K-pop. The research starts with providing a general descriptive overview of K-pop. Following that, quantitative methods are applied to measure and assess the international recognition and global spread of K-pop. Next, a systematic approach is used to identify and analyze factors and forces that have important influences and implications on K-pop’s globalization. The analysis is carried out based on three levels of business environment which are macro, operating, and internal level. PEST analysis is applied to identify critical macro-environmental factors including political, economic, socio-cultural, and technological. On the industrial level, major forces that shape the music industry in which K-pop’s business operates are evaluated based on the framework of Porter’s Five Forces. External environmental analysis is followed by the review of the global strategies of major Korean entertainment companies in achieving their organizational objective of turning K-pop into a successful global business. We identify all the key value-creating activities ranging from talent acquisition to customer relationship management in the value chain of K-pop’s industry, and analyze how each of these activities have contributed to K-pop’s success in the global market. In conclusion, the recent success of K-pop on the global stage can be understood as the rewards for the capability of its internal strategy to anticipate and capitalize new opportunities in external environment.
In a worldwide accessible marketplace with numerous competitors who try to beat prices and quality of services and products, it is vital for online businesses to strive for strategies to be able to survive in a competitive environment and to sustain growth. The company Usbstick-Producer has gained numerous customers in the German market, but nevertheless competes against many businesses which offer similar products to similar prices. Therefore, it is highly important to defend gained market share. Appropriate strategies and investments are necessary to implement in order to attract and retain customers.
The bachelor thesis aims to explore the nature of customer retention and to give the company Usbstick-Producer recommendations regarding possible improvements and customer retention strategies for the German market. The company’s goal is to retain more customers and to ensure customer satisfaction in order to guarantee profitability for the business.
In order to attain the objective of the thesis, a multi-method approach is being used. A literature review is carried out in order to develop a comprehensive analysis and theoretical framework on the topic of customer retention and related concepts. An internal and external analysis are conducted which help to understand the key drivers and most important influencing factors for the business using the PEST analysis, Porter’s five forces analysis and SWOT analysis.
Qualitative research is utilised in order to investigate the practical aspects of the topic in direct relation to the company. Valuable insights and expert opinions as well as experiences are collected during expert interviews in order to develop appropriate strategic recommendations.
The research concludes with strategic recommendations for the company Usbstick-Producer using the collected and analysed data of the literature review and expert interviews. In the conclusion, possible further research topics are assessed and limitations of the research are discussed.
Agriculture in Tanzania is not only the biggest employer, but also it is the highest contributor of the GDP. Apart from being an important sector in the country, it is characterized by small scale subsistence farming which is not mainly profitable. In order to transform the agriculture from traditional to commercial, young people, who make 35% of the entire population, are the main driver however they are facing many challenges. Having that in mind, Tanzanian government has enacted several policies whose main aim is to make it easy for young people to engage in agriculture.
In this bachelor thesis, the agricultural policies which have been enacted by the government to attract young people will be discussed and it will be analyzed if they have brought the impacts desired by the government. In order to do that, a survey was conducted in a district called Bukombe in Tanzania and in one agricultural university which is found in Eastern Tanzania.
The results of the above mentioned studies show that majority of youth policies which have been enacted in Tanzania do not involve youth from the beginning of the preparation. Also, there the general studies found that not many young people are aware of the policies which have been enacted to protect them or make their farming activities easier.
The limitation for this study is that the study sample which is used is from only one district and one university so it may be difficult to compare that the results represent the whole country. Also another limitation is that there are still not many studies which have been conducted in Tanzania for this matter so it is difficult to find the up to date resources. This leads to the resources used to be a bit older and in most of the time to depend on only resources from the websites of government institutions.
The project business in the packaging machine industry is highly volatile. Although the industry is steadily growing, firms face increasing financial constraints due to external, difficult to control, factors. This thesis examines the underlying concepts and processes of a Supply Chain Finance implementation, using the Syntegon Group as an empirical example. Due to the extended payment terms of customers and the currently undergoing refinancing measures, the analysis about potential liquidity increasing measures becomes extremely relevant for Syntegon. The research questions covered focus on cash liquidity increases, working capital improvement and alternatives to Supply Chain Finance solutions.
This research aims to provide an informed recommendation about the implementation of Supply Chain Finance. The research is divided into two major parts. The first part discusses the underlying theoretical frameworks to understand the concept of working capital and supply chain management. These concepts are of great importance for the understanding of Supply Chain Finance and its relevance in today’s globalized world. The second part focuses on a detailed empirical analysis of the Syntegon Group. Hereby, the qualitative research involves expert interviews with various departments of the Syntegon Group. The answers of the interviewees are evaluated based on the different categories. This allows for a direct comparison of the interviewee’s answers.
The quantitative analysis consists of the key figure analyses. These allow an informed statement about the current financial situation of the group. By calculating potential payment term extensions and the consequential cash flow opportunities, an estimation about the benefit of the implementation of Supply Chain Finance can be made. Lastly, the cost-benefit analysis of implementing such a solution versus receiving the money as a bank loan is determined.
The results of the calculation and analyses have shown that payment term extensions offer large cash flow opportunities for the Syntegon Group. Receiving a bank loan in the same amount as the unlocked working capital would result in a lower benefit.
Although further research beyond this thesis is needed, the clear benefits of implementing a Supply Chain Finance solution to increase liquidity are demonstrated.
Die vorliegende Arbeit beschäftigt sich mit der Preisfestsetzung im Bankengeschäft. Aufgrund aktueller Marktentwicklungen, wie der Niedrigzinsphase und wachsender Konkurrenz, müssen Finanzinstitute mehr Wert auf das Preismanagement legen. In diesem Zusammenhang wurden die Methoden der Preisbildung gegenübergestellt und kritisch betrachtet. In einem weiteren Schritt wurde empirisch untersucht, wie Banken aktuell mit diesem Thema umgehen und inwiefern die theoretischen Ansätze in der Praxis angewendet werden. Hierzu wurden über 150 deutsche Bankinstitute befragt. Die Ergebnisse der Onlineumfrage zeigen auf, dass es einen Trend hin zur präzisen Sollmargenkonzeption gibt. Immer mehr Institute wechseln von einer ungenauen Bruttomargenkalkulation zu einer genaueren Deckungsbeitragsrechnung. Zudem erkennen Banken den Bedarf, dass der Fokus zukünftig mehr auf den Kunden gelegt werden muss, um Preisbereitschaften besser ausschöpfen zu können. Nichtsdestotrotz dominieren zurzeit immer noch die Dimensionen Kosten und Wettbewerb bei der Preisfestsetzung.
Modern Customer Relationship Management is becoming more and more demanding. Instead of creating competitive advantages through prices, it is more effective to focus on customer relations and their maintenance. Therefore, corporations have to manage a large amount of information to appeal and to tie customers. Simultaneously, due to the huge spread of mobile devices and the extension of broadband networks communication habits are changing and speed of communication is increasing continuously. Clients and co-workers expect faster responses, not only because of the use of the internet but even more because of the use of mobile services. Finally, the way of working has changed considerably during the past years. Nowadays, employees need flexible access to organizational data as they can manage their working time mostly by themselves. Flexible access may be necessary at customer appointments, at the home office or during business trips. Accordingly, mobile software solutions which are easily operable and tailored to individual requirements are in great demand. Mobile CRM is supposed to accommodate this demand. However, the question arises as to whether mobile CRM is really able to meet the companies’ needs and to solve these issues.
Diese Arbeit untersucht den Bullwhip-Effekt und dessen Einfluss auf die Supply Chain und der jeweiligen Teilnehmer. Da Unternehmen stetig nach Wachstum streben, ist ein reibungsloser Materialfluss entlang der Lieferkette Grundvoraussetzung. Aufgrund von globalen und immer komplexeren Lieferketten, ist die Zusammenarbeit zwischen den Unternehmen nicht immer einfach und optimal. Fehlerhafte Bestellpolitik und das Treffen von irrationalen Entscheidungen stellen für die Unternehmen Probleme dar. Genau diese Probleme spiegelt der Bullwhip-Effekt wider, indem durch mangelnde Kooperation letztendlich Entscheidungen, bezüglich des Bestellvorgangs autonom getroffen werden und diesen Effekt somit bestärken. Diese Arbeit untersucht die Entstehung und den Einfluss des Bullwhip-Effekts auf die Supply Chain. Des Weiteren werden Methoden, die den Bullwhip-Effekt reduzieren bzw. beseitigen können erläutert. Auf Grundlage dieser Erkenntnisse werden die theoretischen Ansätze anhand eines Simulationsbeispiels gestützt und erklärt.
Feasibility of Parylene C for encapsulating piezoelectric actuators in active medical implants
(2023)
Parylene C is well-known as an encapsulation material for medical implants. Within the approach of miniaturization and automatization of a bone distractor, piezoelectric actuators were encapsulated with Parylene C. The stretchability of the polymer was investigated with respect to the encapsulation functionality of piezoelectric chips. We determined a linear yield strain of 1% of approximately 12-μm-thick Parylene C foil. Parylene C encapsulation withstands the mechanical stress of a minimum of 5×105 duty cycles by continuous actuation. The experiments demonstrate that elongation of the encapsulation on piezoelectric actuators and thus the elongation of Parylene C up to 0.8 mm are feasible.
