The proliferation of sensors means that they are increasingly used in harsh environments. A “harsh“ environment refers to extremes of temperature, pressure, shock, radiation and chemical attack. Sensing in harsh environments enables real-time monitoring of combustion processes, subsurface properties, space environments, and critical machine components. In the industrial and automotive fields, the trend to higher power density for motors and actuators is leading to higher operating temperatures for the sensors used to measure position and speed. In addition to this trend there are new applications in the oil- and gas-industry that also require sensors capable of operating at higher temperatures, typically up to 250°C. There is therefore a need for sensor and packaging technologies that can survive these new requirements.
