Pressure Sensor: State of the Art, Design, and Application ...

· There are various types of sensors: thermal sensor, electromagnetic sensor, mechanical sensor, pressure sensor, and others. Pressure is sensed by mechanical elements such as plates, shells, and tubes that are designed and constructed to deflect when pressure is applied. Deflection of the elements must be transduced to obtain an electrical or other output. Pressure sensor can differ in …

Piezoresistive Pressure Sensors | The Design Engineer's ...

In this article we’ll discuss the various types of piezoresistive pressure sensors available, how they work, and their relative merits. Working principle. The basic principle of the piezoresistive pressure sensor is to use a strain gauge made from a conductive material that changes its electrical resistance when it is stretched. The strain gauge can be attached to a diaphragm that recognises ...

Piezoresistive pressure sensor with high sensitivity for ...

· A novel micro-electromechanical systems piezoresistive pressure sensor with a diagonally positioned peninsula-island structure has high sensitivity for ultralow- pressure measurement. The pressure sensor was designed with a working range of 0–500 Pa and had a high sensitivity of mV·V–1·Pa–1. The trade-off between high sensitivity and linearity was alleviated. Moreover, the ...
