MEMS (Micro Electromechanical System) is the integration of microcircuits and micromachines on a chip according to functional requirements, usually in millimeters or microns in size. MEMS technology uses a range of existing technologies and materials in semiconductor technology.
With the rapid development of MEMS technology, gas sensors have also evolved towards miniaturization, intelligence, integration, and low power consumption. Microstructured gas sensors using MEMS technology, combining heating elements and sensitive elements. Optimizing the performance of the gas sensor and greatly improving the sensitivity, reliability, and consistency of the gas sensor.
- The consistency and accuracy of MEMS sensor better than semiconductors, and close to the fuel cell sensor.
- Sensor arrays and comparative signal processing can increase selectivity to target specific gases. It means the results will more stable.
- MEMS provides a reduction in power consumption. Normally, the power consumption of semiconductor needs around 120 mA, but the MEMS-based sensor only needs 15mA. It means the battery can be used longer.
- MEMS sensor can dramatic size reduction, it also can improve some pocket and handheld semiconductor breathalyzer.
