ENERGY CONVERSION DEVICE

摘要

A transducer is described comprising at least one torsion bar, said torsion bar defining a torsional axis, a piezoelectric film arranged on the at least one torsion bar; and electrodes arranged on said piezoelectric film. The transducer may e.g. be used as an energy conversion device, an energy harvesting device, inertial sensor, accelerometer, gyroscope, tilting mirror, torsional actuator, viscometer or to impose a controlled angular rotation.
