⛽ Micro hotplate gas sensor circuit?

A new class of high temperature resistive gas sensors based upon a micro-hotplate SOI structure with a self-heating MOSFET is proposed. Our design is completely compatible with a standard CMOS/BiCMOS SOI process, that permits the integration of control and signal conditioning on the same silicon chip and, thereby, enables volume production at a relatively low unit cost.

micro-sensors such as gas sensors. The main objective of a wide range of research is miniaturized gas sensors with low power consumption. In fact, the majority of gas sensitive materials operate at elevated temperatures. In metal oxide gas sensors MOX, micro-heater is used as a hotplate in order to control the temperature of the sensing layer [10].

micro hotplate. We improve our electro thermal heater model, tacking in account the convective thermal effect that can be described using the COMSOL Thermal Module in stationary regime. In such a way we can propose an explicit thermal flux law. Keywords: Electro-Thermal model, Thermal laminar convection, Filament, Hotplate, Gas Sensor 1.
