<p>Two sectors in an upper semicircle are positively polarized with a plus voltage against an earth (GND), while another two sectors are negatively polarized with a minus voltage against an earth. Two in-phase control signals each with a slowly increasing side of an impulse, e.g. saw-tooth signals, are fed into control channels over a voltage time (U(t)). Independent claims are also included for the following: (A) A multilayered actuator with multiple overlaid piezoelectric actuators; (B) and for an inertia motor with a piezoelectric actuator; (C) and for a step motor with a piezoelectric actuator; (D) and for a method for creating a piezoelectric actuator from a piezoelectric ceramic substrate with four structured electrodes and a back-plate electrode.</p> |
