SensMi: Sensorische Mikroelektronik

Motivation

In the aforementioned project, the task in the field of applied research is to realize magnetoresitive multisensors for position detection in harsh environmentsSensors are finding more and more new applications in automation. Thus their number and the amount of work for installation and maintenance increases. Especially sensors that are mechanically stressed or used under adverse conditions have a limited lifetime. Therefore, the trend is towards sensors without mechanical actuators. With new concepts it is possible to replace mechanical sensors with wear-free sensors...

Challenge

The task is to develop a sensor for , specific applications. In order to adapt the sensor for its task in the best possible way, the environment and the actuator of the sensor are investigated. With this knowledge, a sensor process was developed that can survive in found, harsh environments such as automotive applications. The second criterion is durability. For this reason, only wear-free methods or methods that are suitable for the stresses are used. The preference is for capacitive, inductive, piezoelectric effects and optoelectronic sensing of sensor signals. Most sensors are designed in such a way that they can be used for a wide range of applications...

Research activities

Besides the investigation of different methods, the integration into stable mechatronic environments like printed circuit boards is in the foreground.
