What is Piezoelectric Sensor - Construction, Working ... Piezoelectric Effect. Piezo is a Greek term signifying “press” or “squeeze”.Piezoelectricity (also called the piezoelectric effect) is the presence of an electrical potential across the sides of a crystal when mechanical stress is applied by squeezing it. In working system, the crystal acts like a tiny battery with a positive charge on one face and a negative charge on the opposite face.
