Piezoelectric Sensor in Pakistan

A piezoelectric sensor or element is a device that uses the piezoelectric effect, it is basically a device which converts voltage to vibration and vibration to voltage. It normally comes in handy to measure knock (knock sensor) or vibration (vibration sensor).

Piezoelectric Transducer Piezo Sensor or Piezo Elements work on the principle of the piezoelectric effect. This effect measures changes in pressure, stain, temperature, acceleration, and force in the form of electrical charge or voltage. The materials which work under the piezoelectric effect are piezoelectric crystals, ceramic, bone, some proteins, and DNA.

Piezoelectric transducers are a type of electroacoustic transducer that convert the electrical charges produced by some forms of solid materials into energy. The word “piezoelectric” literally means electricity caused by pressure.

Piezoelectricity is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat.
