Conca (TU Kaiserslautern), J. Rühl (LTI Drives), Dr. B. Leven (TU Kaiserslautern), Prof. Dr. B. Hillebrands (TU Kaiserslautern), Dr. J. Gerber (director of the magnetic industry association INNOMAG), Dr. R. Slatter (Sensitec, CEO).

The conclusion meeting for the Spin Technology Platform (STeP) took place on February, 12, at the facilities of our industrial collaborator Sensitec in Mainz. Together with the Johannes Gutenberg University in Mainz, STeP aims to the development of new concepts and measurement methods for the magnetic sensor technology. STeP is a clear example of technology transfer between universities and industries, where relevant results on lab level are prepared to be converted into real applications. The magnetic sensor technology finds application in the automotive industry, in robotics or for industrial automation processes.

During the meeting, the main scientific results were presented to a delegation of people from the industry and politics. In the center of the photo above, a model of the elevators system of the Taipei building in Taiwan is shown. This model explains an example of a real application of magnetic sensors for positioning and contains the same sensors used in the actual building in Taipei (courtesy of ELGO Electronics, developer of this system).

In addition, the partner project TT-DINEMA (Technology Transfer Service Centre for New Materials) was also presented. The aim of the TT-DINEMA project is to establish a service center for new material concepts for various fields, ranging from solar technology through medical technology to thermoelectrics.
