AN ELECTRO-MECHANICAL DEVICE HAVING A PIEZOELECTRIC ACTUATOR

摘要

AN ELECTRO-MECHANICAL DEVICE HAVING A PIEZOELECTRIC ACTUATORAbstractEmbodiments provide an electro-mechanical device. The electro-mechanical device includes a piezoelectric actuator, a first contact electrode and a second contact electrode. The first and second contact electrodes are moveable between a configuration in which they are electrically connected together and a configuration in which they are electrically isolated from each other. The piezoelectric actuator has a deflection element controllable by a first control electrode and a second control electrode. The electro-mechanical device is configured such that a voltage of one polarity applied across the first and second control electrodes causes a deflection of the deflection element which urges the first and second contact electrodes together.FIG. 1
