The Leistungszentrum Elektroniksysteme (LZE) is a joint initiative of the Fraunhofer-Gesellschaft, Fraunhofer IIS, Fraunhofer IISB, and Friedrich-Alexander University Erlangen-Nürnberg (FAU), in addition to other non-university research institutes and various industry partners. The center grew out of many years of intense cooperation between the Fraunhofer institutes in Erlangen and FAU, in addition to the unique concentration of electronic systems research activities and industries based in Nuremberg-Erlangen. Research excellence and joint planning have created the foundation for a comprehensive, long-term strategic partnership between Fraunhofer, FAU and the electronics industry. The LZE, which launched a pilot phase in January 2015, is being funded by the Bavarian Ministry of Economic Affairs- and Media, Energy and Technology. The pilot phase focuses on four projects:
- The DC backbone with power-to-gas coupling offers a complete solution for the efficient integration of short-term and longterm energy storages within local microgrids. This comprises the optimized combination of highly efficient lithium-ion batteries for compensation of short-term fluctuations and a hydrogen storage system for the long-term storage of energy. The generated hydrogen is stored under ambient conditions by loading a liquid organic hydrogen carrier (LOHC) within a chemical reactor. One main advantage of that storage technology is the very high energy density, which allows the compact prototype setup of the chemical energy storage system within a 20 ft-Container.
- The ability to transfer power in small moving systems is required for a wide range of applications such as wind power systems with electronics integrated in the rotor blades or highly-automated Industry 4.0 production platforms. The goal of the project is to develop a technology for the contactless transfer of power and data in small moving components in harsh environments that will offer advantages such as: Bidirectional power and data transfer; Wear-free alternative to failureprone cable-based solutions; Improved safety for manufacturing systems, the chemicals industry and medical technologies; Specifications that are closely aligned with the application through active involvement of the industry partners; International visibility through scientific publications
- When it comes to grid independent systems, energy efficiency is one of the key challenges in the area of electronics technology, especially for daily electronic accessories (wearables) used in sports and fitness applications. The aim of this project is to combine energy efficient acquisition of physiological raw signals with reliable processing of biosignals and activity parameters from mobile systems. As a first step a functional demonstrator was developed that combines the RedFIR® real-time localization and FitnessSHIRT technologies. This will allow the system to simultaneously capture positioning and movement data as well as vital parameters such as heart rate and respiration. This information is subsequently used to create an optimized and individual training concept.
- Pursuing a high-performance logistics solution, this project involves the implementation of an asset tracking system, including the development of the electronics for the gateways and location beacons, as well as a miniaturized wireless tag integrated into the tracked asset. An energy-saving wireless solution is especially important for this application. The tag electronics consist of a three-band wake-up receiver with a current consumption of 6 µA, plus an efficient twoband transmitter. The tag will be completely powered with energy harvesting technology for permanent autonomous operation.
