HIGH TEMPERATURE BIMORPH ACTUATOR

A bimorph actuator has been found that uses commonly available piezoelectric material and is operational up to about 150° C. or one half of Curie temperature, in that it does not exhibit depolarization due to negative electric fields and/or elevated temperature. This result is accomplished by drivin...

Zusammenfassung:A bimorph actuator has been found that uses commonly available piezoelectric material and is operational up to about 150° C. or one half of Curie temperature, in that it does not exhibit depolarization due to negative electric fields and/or elevated temperature. This result is accomplished by driving both piezoelectric materials with a positive electric field along the polarization direction.
