11/22 · Piezoelectric materials are one of the advanced materials that are widespread around us, although they are unknown to the public at large. The word “piezo” stems from the ancient Greek word piezein, which means “to press” or “to squeeze”. “Piezoelectricity” thus literally means “pressure-induced electricity”.
