How Piezoresistive Pressure Sensors Work.
A Piezoresistive Pressure Sensor contains several thin wafers of silicon embedded between protective surfaces. ... The Wheatstone bridge runs a small amount of current through the sensor. When the resistance changes, less current passes through the pressure sensor.
For example,
the biomedical field uses piezoresistive sensors as tools to measure blood pressure, while the automotive industry uses them to gauge oil and gas levels in car engines. In a piezoresistive pressure sensor, a piezoresistor is usually implanted in the surface of a thin silicon diaphragm
