Piezoelectric Amplifier

With the application of Disributed Compliant Design, the performance capabilities of this actuator far exceed that of currently competing piezo-amplifier systems and bender-type configurations in terms of block force, stroke, and frequency capability - opening the door to new, compact, high-power actuation systems..

Actuator using Distributed Compliance

Applying a compliant monoform mechanism to a piezoelectric actuator greatly increases the working envelope of this sort of smart material actuator. Piezoelectric translators (transducers) are high precision ceramic actuators that convert electrical energy directly into linear motion. They are ideal for high speed, or force, with virtually unlimited resolution applications such as semiconductor testing and inspection, super-resolution microscopy, bio-nanotechnology, astronomy and aerospace technology. Because of the compliant mechanism The performance capabilities of this actuator far exceed that of currently competing piezo-amplifier systems and bender-type configurations in terms of block force, stroke, and frequency capability - opening the door to new, compact, high-power actuation systems.

65x amplifier mechanism made of titanium

In this demonstration, a piezoelectric stack operates incorporating a monoform compliant 65x amplifier mechanism made of titanium. Each actuator-amplifier weighs just 17 grams and measures 22.5 x 53 x 55mm. It provides 41. N Black Force and 2.97 mm free-displacement. he first natural frequency of the system is 300 Hz.
