Cambridge CMOS Sensors MEMS Micro-hotplate technology provides a unique silicon platform for the Metal Oxide (MOX) gas sensors, enabling sensor miniaturisation, significantly lower power consumption and ultra-fast response times.

The resistive Micro-hotplates are fabricated using a high reliability silicon dioxide membrane and include an embedded tungsten heater acting as a heating element for the MOX based sensing material. The micro-hotplate can be used to heat the MOX material to up to 450°C and the electrical resistance of the MOX sensing material can be monitored to detect the target gas. With extremely fast heater cycling times, temperature modulation techniques can be used to reduce the device power consumption and implement advanced gas sensing methods, resulting in class leading gas sensing performance.

Advanced algorithms support the MOX gas sensors family, for maximum sensitivity, selectivity, drift compensation, and for self-calibration; enabling easy and timely integration into a wide range of products and applications.
