Piezoelectric Sensor

Piezoelectric sensor for mechanical forces & vibration

Piezoelectric sensor utilises piezoelectric effect to measure mechanical forces such as pressure, vibration etc. Piezoelectric crystals convert mechanical energy into electric energy and vice versa. When a pressure is applied to a piezoelectric crystal, a proportional electric voltage is generated. Similarly, when an electrical voltage is applied across the crystal, a proportionate mechanical energy is developed. Piezoelectric sensors are manufactured such piezoelectric crystals. These sensors are generally used to measure sudden mechanical variations, vibrations and fluctuations and these are not suitable for continuous forces. A continuous pressure applied on a crystal will not produce accurate electric signals. For such requirements, a pressure sensor would be ideal.
