Piezo Bending Actuators

Piezo bending actuator consists of one piece of metal plate and one/two ceramic plates, piezo bending actuator will shorten or elongate in radial driven by positive harmonic alternating current or pulsed electrical signals, metal plate will become deformed at the same time, so the volume of piezo pump cavity will be changed alternately. The pressure difference between the inner and outer cavity of the pump under the action of the valve body push forward the constant flow of gas or liquid.

The piezoelectric ceramic bending type actuating sheet is composed of a single piezoelectric ceramic sheet or a double piezoelectric ceramic sheet and an intermediate elastic substrate.Piezoelectric ceramic twin crystals that produce corresponding bending displacements driven by DC voltage.
