What is a piezoresistive pressure sensor?
Piezoresistive pressure sensors are one of the very-first products.
Those products are widely used in biomedical applications,
automotive industry and household appliances.
The sensing material in a piezoresistive pressure sensor is a diaphragm,
formed on a silicon substrate, which bends with applied pressure.
A deformation occurs in the crystal lattice of the diaphragm because of that bending.
This deformation causes a change in the band structure of the piezoresistors,
that are placed on the diaphragm,
leading to a change in the resistivity of the material.
This change can be an increase or a decrease according to the orientation of the resistors.
This variation in the sensitivity of the sensor will enlarge the application areas of the sensors.
Those sensors will also include temperature sensors.
With those, tem perature information can be obtained and can be used for temperature compensation purposes.
How does a piezoresistive pressure sensor work?
A Piezoresistive Pressure Sensor contains several thin wafers of silicon embedded between protective surfaces. The surface is usually connected to a Wheatstone bridge, a device for detecting small differences in resistance. The Wheatstone bridge runs a small amount of current through the sensor. When the resistance changes, less current passes through the pressure sensor. The Wheatstone bridge detects this change and reports a change in pressure.
