<p>A flexing piezoelectric bimorph (10) is formed, preferably from piezoelectric polymers (14, 16) having two metallized surfaces (19, 20), by bonding together two metallized surfaces (19, 20) to provide a pair of piezoelectric polymer layers (14, 16) arranged with substantially similarly oriented polarization. The outwardly facing metallized layers (22, 24) bonded on the opposite facing surfaces from the other two conducting layers of the bimorph. The control circuit (12) is connected so that applied potential and the outwardly facing two conducting layers (22, 24) are connected to ground in order to drain away static charge and shield the polymers (14, 16) from extraneous electric fields. The control potential (34) is electrically connected to the interposed central metallized layers (19, 20) which are bonded together and form the second electrode (18) for applying the appropriate electric fields to the bimorph (10).</p> |
