BiSWind - Component-integrated sensor technology for power transmission elements in wind turbines

The aim of the project is to research an energy-autonomous sensor platform which, integrated on a rotating shaft, can perform sensory tasks, in this case the measurement of torque, temperature and vibrations, and transmit measured values wirelessly to a receiver module for further data processing. The platform is characterized by an integration of micro-sensor technology and micro-electronic components as well as a transmitter and receiver module, so that a miniaturized and self-sufficient solution is achieved, as is required by the application (wind energy). For this purpose, specially optimized complex LTCC-based electronic modules adapted to the waveform are implemented. For the first time, a miniaturized solution is to be achieved by curving otherwise flat circuit carriers, so that integration in places with minimal space is possible and new markets can be opened up by the consortium partners through the functional expansion that can be achieved in this way. In order to achieve this, sensory components are implemented both directly integrated on the shaft and on the curved LTCC circuit carrier to be researched and connected to the evaluation circuit.
