摘要： A surface acoustic wave actuator is disclosed which includes unidirectional interdigital transducers disposed on both sides of a vibrator and an electrical combiner. One of the unidirectional interdigital transducers and external power supply are connected to an input port, and the other unidirectional interdigital transducer is connected to an output port of the electrical combiner. The electrical combiner combines input energy from an external power supply and surface acoustic wave energy is electrically converted by one of the unidirectional interdigital transducers, and input to the other unidirectional interdigital transducer. Surface acoustic waves excited by the other unidirectional interdigital transducer propagates on a vibrator, and is input to the other unidirectional interdigital transducer again after passing one unidirectional interdigital transducer and the electrical combiner. A relative movement member is pressed against the vibrator for generating driving force via a friction force so that the relative movement member implements relative movement to the vibrator.

摘要： On a substrate are configured piezoelectric elements composed of a mirror device, piezoelectric thin films, electrodes, and elastic members, and application of a voltage to the electrodes causes flexure deformation in the piezoelectric thin films, so that the mirror device is actuated. A plurality of the piezoelectric elements are arranged in parallel with a longitudinal direction thereof, and torsion springs are provided so as to extend in a direction orthogonal to the longitudinal direction and so as to hold the mirror device in connection with the substrate. The mirror device is connected to the piezoelectric elements through strain absorbers. In such a configuration, the torsion springs serve as a rotation axis, and the mirror device is inclined about the rotation axis.
