  • Abstract
    A torsional microactuator was developed using standard bulk lead zirconium titanate placed upon a small rectangular prism made from phosphor bronze, with a tapered conical end serving as a horn and a carefully machined interior to improve the actuator´s response. The results of testing indicate torsional motion was obtained from the device, with torsional vibration velocities of 295 mm/s at 190 kHz being obtained at 27.5 VRMS at the output, amounting to 19,320 deg/sec vibration velocity along the outer circumference of the tip.
