Micro actuators and sensors are the fundamentals of miniaturized, intelligent and networked systems. Since 2012, a completely new type of powerful actuators has been developed and tested in the project group Mesoscopic Actuators and Systems MESYS of the Fraunhofer Institute for Photonic Microsystems IPMS in cooperation with the Brandenburg University of Technology BTU Cottbus - Senftenberg. Electrostatic actuators are used to move plates or bend cantilevers and therefore deflect light or laser beams, move liquids or generate ultrasound. The researchers aim is to solve fundamental problems and limitations of conventional electrostatic actuators, for which large deflections can only be realized in combination with large dimensions and high energy consumption. Using a suitable lever principle, the researchers developed a new class of electrostatic bending actuators that of an extremely compact design, large deflections and no hysteresis. Using conventional silicon manufacturing processes, these new actuators can be integrated directly into semiconductor components and CMOS circuits, thus enabling cost-effective volume production. Thanks to high performance and scalability of the patented actuators, various fields of application and design possibilities can be adressed. Optical applications are, for example, high-precision positioning drives of micro-tilt mirrors or lens systems for laser beam deflection, pico projectors, 3D-endoscopes or microscopic applications. NED-actuators are also suitable as optical switches or the highly precise positioning of optical waveguides. Furthermore, a variety of non-optical applications can be addressed, such as micro pumps and valves for microfluidic systems or as miniaturized loudspeakers for hearing aids, smartphones and wearables. Contrary to existing micromechanical loudspeakers NED-based speakers offer both an extremely compact design and high performance.
The Ferdinand-Braun-Institut, Leibniz-Institut fuer Hoechstfrequenztechnik (FBH) researches electronic and optical components, modules and systems based on compound semiconductors. These devices are key enablers that address the needs of today’s society in fields like communications, energy, health and mobility. Specifically, FBH develops light sources from the visible to the ultra-violet spectral range: high-power diode lasers with excellent beam quality, UV light sources and hybrid laser systems. Applications range from medical technology, high-precision metrology and sensors to optical communications in space. In the field of microwaves, FBH develops high-efficiency multi-functional power amplifiers and millimeter wave frontends targeting energy-efficient mobile communications as well as car safety systems. In addition, compact atmospheric microwave plasma sources are devellopped for medical applications or surface coating.

Fraunhofer IZM specializes in industry-oriented applied research. Fraunhofer IZM develops assembly and interconnection technology, also known as electronic/photonic packaging. Almost invisible and undervalued by many, electronic packaging is at the heart of every electronic application. Our technologies connect the individual components, protect components and devices from vibration and moisture, and reliably dissipate heat. Fraunhofer IZM thus ensures that electronic devices continue to function reliably in even the harshest conditions – we even integrate electronics into golf balls. Modern packaging technologies make developing smaller and smaller products possible. We process ICs thinner than a sheet of paper.
The business area Photonics combines Fraunhofer IZM’s skills and know-how to tackle challenges in telecommunication, data communication, light generation, materials processing and optical sensors.
We pursue different goals in each of these areas. In communication, broadband capacity, power efficiency, high, heterogeneous packaging density are the main focus, while in lighting, we aim to improve high power density, thermal management, multifunctional integration, wavelength conversion and beam guiding. In sensor technology, application-specific heterointegration of excitation source, sensor and analysis electronics take center-stage. However, three goals are pursued across all these areas: volume adjusted manufacturing technology, cost-efficiency and high yield.
Non-profit private industrial research institute, realisation of projects in the field of fundamental and applied research especially in Photonics, X-ray physics and X-ray technology. Main competence: X-ray analytics for technological process control Photonic crystal fibres for laser applications. Organisation of workshops, conferences and exhibitions in these fields also for further education. Since 2001 every two years the conference PRORA “X-ray analytics for technological process control will be organised by IAP including an industrial exhibition of leading manufacturers of instruments for scientific and industrial applications, participants mainly from Germany and other European countries.
Technical University Wildau – A Competent Partner for Commercial Businesses and Scientific Institutions
The opening of the Technical University Wildau in 1991 has resulted in academic teaching as well as scientific research and development becoming firmly established and highly esteemed in the region to the south-east of Berlin. Not only businesses and scientific institutions, but also public administrative bodies all profit directly from this development by being able to recruit Wildau graduates directly as young specialists and managers. They also benefit from R&D cooperation and projects, networks for knowledge and technology transfer in addition to further-training programmes which can be tailor-made for companies and a wide range of institutions.
Documented quality control and direct practical relevance are the outstanding hallmarks of 28 degree courses on offer, ranging from engineering, business and administration to legal studies, available both on campus and via distance learning. With more than 4,200 students Wildau is the biggest university in the regional state of Brandenburg. Changing from diploma to bachelor and master programmes has considerably strengthened the academic character of the Technical University Wildau.
Photonic, Laser and Plasma Technologies
Professor Sigurd Schrader’s working group is active in the areas of photonics, optical technologies, laser and plasma technologies, both in teaching and applied research. This group is involved in the following fields:
- Material syntheses and experiments
- Producing optoelectronic elements and components
- Characterizing optoelectronic elements and components
- Process characterization and optimization
This research group cooperates closely with industrial partners, mainly small and medium-sized companies situated in the Berlin-Brandenburg capital region. Additionally, as a participant in national and international networks it has considerable contact with research institutions and universities. There is also direct cooperation on a contractual basis with the IHP Leibniz Institute for Innovative Microelectronics Ltd in Frankfurt an der Oder, which had led to their joint research and training centre (Joint Lab). The main focus of this activity is to develop concepts for innovative silicon based elements and technologies for high-speed electronics and photonics. Among Joint Lab’s activities are experiments aimed at generating graphic layers in order to attain higher limit frequencies up to the terahertz level. This may lead to new applications in sensorics and medical technology.
