Design and Simulation of MEMS Gas Sensor Topologies for ...

· MEMS gas sensors are capable of detecting gas traces to the level of ppt (parts per trillion). The most commonly used MEMS topology for gas sensing is based on metal oxide thin films along with micro heaters. However this topology is not suitable for inert gases because they do not react with the metal oxide to change the conductivity of the thin film. Hence we need to design different ...
