Piezoelectric actuator / piezo actuator
A piezo bending actuator (bimorph) is composed of two thin panels of piezoceramic elements bonded together with a supporting material. By wiring these two piezo elements in such a way as to make one elongate and the other contract by applying voltage, inflection deviation occurs conforming to the waveform of the applied voltage. Bimorphs are operated in d31 mode. We use excellent materials and design products corresponding to various application: piezoelectric actuator for knitting machine, valve, fan, piezoelectric pump, piezoelectric braille display etc.
