Development of products using piezoelectric ceramic elements

Piezo has characteristic which is belonging to a certain type of crystal. Piezo can change shape by energizing and can generate electricity by pressure. Piezoelectric element, which can transform electric potential and displacement, is one of mysteries generated from physical phenomena. Piezoelectric element is our key technology. We develop various products which have high usability at different situations, by using Piezoelectric ceramic elements.

Elementary Technology of Piezoelectric Ceramic elements
Piezoelectric Ceramic Elements is the element which is to produce the automatic and continuous deformation (vibration) by supplied electricity then to generate charges which are proportional to pressure by applying pressures (forces). And Piezoelectric Bone Conduction speaker/microphone is the system to recognize vibrations as a sound and catch the voice by the vibrations to convert them into electric signals.
