Advantages & Disadvantages of Piezoresistive Pressure Sensors

June 18, 2021

Piezoresistive pressure sensors, as the earliest type of pressure sensor, are critical devices in a variety of control and automobile applications.

Piezoresistive pressure sensors can be used for absolute, gauge, relative or differential measurements. The construction is simple which means low cost and durability. They're robust with good resistance to shock, vibration, and dynamic pressure changes, suitable fore a wide range of pressure measurements. The output is stable over time. And the readout circuits are very simple and enable high-resolution measurement

The main disadvantage of piezoresistive pressure sensors is that they may be affected by the ambient temperature, which will produce zero temperature drift and sensitivity temperature drift, while temperature compensation can be done to reduce the impact.
