Heat-resistant capacitors: Stability at up to 300 degrees
Heat is one of the worst enemies of electronics. It can disrupt functionality and cause electronic components to age more quickly, or even destroy them. Now Fraunhofer researchers have developed a capacitor that can withstand temperatures of up to 300 degrees Celsius.
New procedures of post-processing serve the integration of sensors with electronics onto a microchip. Deploying these high-end sensors in thermography and the health sector is part of the special know-how of the institute.
High temperature electronics enable the application of microelectronic circuits within a temperature range of up to 250 °C. Ordinary electronics already reach their limits at 125 ºC under such harsh conditions.
Install, solder, saw – on the Germany-wide “Girls’ Day” the Fraunhofer Institute
for Microelectronic Circuits and Systems IMS in Duisburg enabled a peek
behind the scenes of the research institute for interested students. For the
students there was not only a lot to see, but also much to experience.
Vision 12 µm: The new, extremely small microbolometers of Fraunhofer IMS
Uncooled infrared-detectors measure the thermal radiation of their environment and depicture the temperature distribution of a scene. Core of these detectors is a thermal sensor element, the microbolometer. Now the Fraunhofer Institute for Microelectronic Circuits and Systems IMS has developed a new generation of microbolometers: extra small and therefore especially affordable. The small size is a large advantage for mobile applications. These tiny sensors can be applied in, for example, helmet cameras of firefighters. The possibility to produce them cost-effective, makes them especially interesting for the mass market. Thanks to an innovative structure the new microbolometers are despite of their small size extremely efficient.
