Thermoelectric infrared sensors enable noncontact temperature measurement and the generation of thermal images. They are already in use today in process monitoring, building automation, and security technology. However, the performance of current systems is limited by the thermocouple materials used. The new project addresses this challenge by employing significantly more efficient thermoelectric materials and a novel MEMS device concept. <\/p>\n
The targeted improvement in temperature resolution opens up numerous new fields of application. In the medical field, future applications could be developed to support early cancer detection or the detection of externally visible inflammation. In the context of age-appropriate living, the sensors also enable new solutions, such as the reliable detection of falls or emergency situations in the home.<\/p>\n
Furthermore, autonomous vehicles benefit from the higher sensitivity of the sensor arrays. For industrial applications, new possibilities are opening up in thermography and process monitoring. In addition, the use of the sensors in cost-effective solutions for contactless temperature measurement opens the door to further application and market segments. <\/p>\n
Fraunhofer IPMS is taking on key roles in the project related to the development of MEMS technology. This includes the integration of novel thermocouple layers, the development and optimization of the necessary manufacturing processes, and the production of demonstrator chips. In addition, strategies are being developed to integrate the new materials into the institute\u2019s 200-mm production line in the future.<\/p>\n
The project partners will initially demonstrate the developed technologies using passive sensor arrays. In a subsequent development phase, these will be used to create active sensor arrays with integrated CMOS drive electronics. The demonstrators developed in the project aim to achieve a technology readiness level (TRL) of 4.<\/p>\n
