Como funcionam os sensores de pressão MEMS em temperaturas extremas de -40°C?
The operating principle of MEMS pressure sensors is based on the piezoresistive effect of silicon materials. When the temperature drops to -40°C, the physical properties of the silicon material change, which may lead to a decrease in the sensitivity and accuracy of the sensor. In addition, extreme low temperatures may cause thermal stress changes in the encapsulated material, affecting the stability of the sensor.
