PublicationSensor Systems for Extremely Harsh Environments( 2023-10-31)Sensors are key elements for capturing environmental properties and are today indispensable in the industry for monitoring and control of industrial processes. Many applications are demanding for highly integrated intelligent sensors to meet the requirements on safety, clean and energy efficient operation or to gain process information in the context of industry 4.0. While in many everyday objects highly integrated sensor systems are already state of the art, the situation in an industrial environment is clearly different. Frequently the use of sensor systems is impossible, due to the fact that the extreme ambient conditions of industrial processes like high operating temperatures or strong mechanical loads do not allow a reliable operation of sensitive electronic components. Eight Fraunhofer Institutes have bundled their competencies and have run the Fraunhofer Lighthouse Project ‘eHarsh’ to overcome this situation. The project goal was to realize sensor systems for extremely harsh environments, whereby sensor systems are not only pure sensor elements, rather containing one or multiple sensor elements and integrated readout electronics. Various technologies which are necessary for the realization of such sensor systems have been identified, developed and finally bundled in a technology platform. These technologies are e. g. MEMS and ceramic based sensors, SOI-CMOS based integrated electronics, board assembly and laser based joining technologies. All these developments have been accompanied by comprehensive tests, material characterization and reliability simulations. Based on the platform a pressure sensor for turbine applications has been realized to prove the performance of the eHarsh technology platform.

PublicationSensor Systems for Extremely Harsh Environments( 2022)Sensors are key elements for the detection of environmental properties and are indispensable in industrial applications for process monitoring and intelligent control of processes. While highly integrated sensor systems are already state -of-theart in many everyday areas, the situation in an industrial environment is significantly different. The use of sensor systems is often not possible because the extreme environmental conditions of industrial processes such as high operating temperatures or strong mechanical loads do not allow the reliable operation of sensitive electronic components. As part of the Fraunhofer Lighthouse project eHarsh, eight institutes have bundled their competencies and created a technology platform as a basis for the development of sensor systems for extremely harsh environments.

PublicationSmart sensor systems for extremely harsh environments( 2021)Sensors systems are key elements for capturing environmental properties and are increasingly important in industry 4.0 for the intelligent control of processes. However, under harsh operating conditions like high temperatures, high mechanic load or aggressive environments, standard electronics cannot be used. Eight Fraunhofer institutes have therefore bundled their competencies in sensors, microelectronics, assembly, board design, laser applications and reliability analysis to establish a technology platform for sensor systems working under extreme conditions.
