HANNOVER MESSE 2016

Fraunhofer ENAS exhibits together with the Center for Microtechnologies of TU Chemnitz and the WiTech GmbH at the IVAM Product Market "Micro, Nano & Materials" at the HANNOVER MESSE 2016.

The institute shows the following highlight topics:

MEMS spectrometers
A narrow-band, electic tunable filter for the infrared wavelenght range between 3 µm and 11 µm is introduced. The filters are designed a robust, micromechanical chips and are appropriated for the application in smallest infrared spectrometers. Different filters as well as spectrometer prototypes are exhibited. The components are applied in systems for on-line measurement of gas elements, in medical engineering, process monitoring, portable safety equipment and in wireless sensor networks.
Furthermore, a NIR MEMS grating spectrometer is shown. The spectrometer is a joint development with the TQ Systems GmbH in Chemnitz.

Surface technologies
Various technologies for nanostructuring eg. nano imprint and e-beam lithography as well as coating with parylene or metalization of surfaces ar introduced. Coating with parylene is a method to encapsulate sensor systems and implants. Therefore, different material combination are investigated within this new technology at the Fraunhofer ENAS. The coating has to be biocompatible, very stable and reliable. Further processes as plasma pre-treatment and silanization are integrated into the technology during the encapsulating process to enhance the layer adhesion.

Wireless energy transmission
The WiTech GmbH introduces a technology solution for wireless energy and data transmission. The technology can be integrated in various surfaces. Jörg Euskirchen, the CEO of WiTech GmbH, explains: “The WiTech system is an infrastructure solution for wireless power and data transmission to mobile devices and can substitute the power socket.” The WiTech system finishes the cable spaghetti in offices and industrial environments. In cooperation with Fraunhofer ENAS, the WiTech GmbH develops a system of smart receiver and transmitter antennas. The transmitter is integrated invisibly into work surfaces in industrial, public or private environments. If a mobile device with integrated receiver unit is placed on such a state or mobile surface, the two parts of the systems start the communication and transmit energy and data. The antenna array of the transmitter enables a free positioning of the devices on the surface, a good efficiency and high security. The WiTech GmbH shows a wireless monitor as one possible application and offers evaluation kits of the technology at the Hannover Messe.
