capacitive pressure sensors

Capacitive pressure sensors detect changes in pressure by measuring variations in electrical capacitance. They consist of two conductive plates separated by a flexible insulating material, called a dielectric. When pressure is applied, the distance between the plates changes, altering the capacitance. This change is measured electronically, allowing precise determination of pressure levels. Because they respond quickly and can be very sensitive, capacitive pressure sensors are used in applications like medical devices, industrial measurement, and consumer electronics, providing accurate, reliable pressure readings without needing mechanical parts that wear out easily.
