semiconductor distortion gauge

Definition

The appropriate product category Pressure Sensors: A distortion gauge that operates using the following principle. The kinetic potential of the electrons in a semiconductor changes when the crystal structure of the semiconductor is distorted. This changes the carrier mobility in the semiconductor, resulting in a change in the electrical resistance. In a pressure sensor, external pressure distorts a diaphragm, causing distortion in the resistor section in the gauge. A voltage thus is output that is proportional to the pressure.
