Bimorph Actuators

Description:

A solderable conductive central electrode is bonded with two piezoelectric ceramic plates. Both piezoceramic plates are poled in the same direction (Parallel Poled) as shown in the attached side view drawing. The polarity of the bimorph actuator is positively marked on the top electrode as shown in the attached plan view drawing. The surface of the bimorph actuator is coated with special protection varnish.

Driving Voltage: 150 Volts in the polarized direction
Operating Temperature: -250to 70 C
Storage Temperature: -40 to 85 C

Application:

A piezo ceramic flexure element which achieves approximately 20% greater displacements when compared to conventional piezo bimorph elements.

These advanced piezo elements are suited for applications as actuators,fuel injection valves, sensors, optical positioning,reading aids for the blind, textile machines and a host of others.
