High-precision, piezoresistive pressure measurement technology in a wide array of designs. Piezoresistive pressure sensor is also called solid state pressure sensor. It is different from the adhesive strain gauge that needs to indirectly feel the external force through the elastic sensitive element, but directly feels the measured pressure through the silicon diaphragm. 1. Piezoresistive strain gauges are a semiconductor material which changes in resistance when the material stretched or compressed. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) The simple construction means low cost and durability. The current state-of-the-art piezoresistive sensors are mainly constructed via dispersion of conductive nanofillers in an elastomer matrix making their performance strongly reliable on the degree of dispersion. The magnitude of the change can be 100 times greater than the resistance change produced in a metal strain gauge. A piezoresistive internal combustion engine sensor.
