Design and Application of a High Sensitivity Piezoresistive Pressure Sensor for Low Pressure Conditions

Sensors, 2015
In this paper, a pressure sensor for low pressure detection (0.5 kPa–40 kPa) is proposed. In one structure (No. 1), the silicon membrane is partly etched to form a crossed beam on its top for stress concentration.
