Introduction
MEMS CO sensor is a miniature metal oxide semiconductor gas sensor based on MEMS micro hot plate technology, used to detect the toxic gas CO in the air. The production of the sensor combines MEMS silicon substrate technology, thin film technology, thick film technology and ceramic packaging technology. The patented nano-frame gas sensing layer is deposited on top of the micro hot plate and the interdigital electrode, thereby generating a conductivity that depends on the concentration of harmful gases.
