Piezo is derived from the Greek πιέζω, which means to squeeze or press, and may refer to: *

PIEZO1 Piezo1 is a mechanosensitive ion channel protein that in humans is encoded by the gene ''PIEZO1''. Piezo1 and its close homolog PIEZO2, Piezo2 were cloned in 2010, using an siRNA-based screen for mechanosensitive ion channels. Structure and fun ...

Piezoelectric sensor A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix ''piezo-'' is Greek for 'press' or 'squeeze'. ...

, a device that converts differences in physical force to generate voltage *

Piezoelectric speaker A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sou ...

Piezometer A piezometer is either a device used to measure liquid pressure in a system by measuring the height to which a column of the liquid rises against gravity, or a device which measures the pressure (more precisely, the piezometric head) of groundwa ...

, a device that measures the pressure of groundwater at a certain point *

Piezoresistive effect The piezoresistive effect is a change in the electrical resistivity of a semiconductor or metal when mechanical strain is applied. In contrast to the piezoelectric effect, the piezoresistive effect causes a change only in electrical resistance ...

, a change in the electrical resistance of a material in response to mechanical stress * Piezorina, a genus of South American bird *
