A Novel Stick–Slip Piezoelectric Actuator Based on a Triangular Compliant Driving Mechanism
IEEE transactions on industrial electronics (1982. Print), 2019There is a growing demand for positioning actuators with a higher resolution, accuracy, speed, and driving force. Various piezoelectric actuators have been proposed to meet these requirements; however, they all have inherent limitations.

Smart materials and structures (Print), 2020
Motion speed is an important parameter of stick-slip piezoelectric actuators. However, most of the existing stick-slip piezoelectric actuators achieve a high motion speed by operating under a quite high driving frequency.

Piezoelectric Actuator Designs
2008Piezoelectric actuators are getting immiscible parts of many important electromechanical and smart systems. Smart systems consist mainly of sensors, actuators, and signal processing units. Actuators are the responding units of many smart systems including those for active vibration and noise control, valve, shutter, focal lens, and many others ...

A walking type piezoelectric actuator with two umbrella-shaped flexure mechanisms
Smart materials and structures (Print), 2020A walking type piezoelectric actuator with two umbrella-shaped flexure mechanisms is proposed to reduce the backward motion. By utilizing two umbrella-shaped flexure mechanisms which could be treated as two ‘legs’, the ‘walking’ motion is accomplished ...

A novel stick-slip piezoelectric actuator based on two-stage flexible hinge structure.
Review of Scientific Instruments, 2020The traditional stick-slip piezoelectric actuator uses a single flexible hinge structure, and the output force of the piezoelectric stack is greater than the clamping force between the driving foot and the slider, resulting in a small working stroke ...

Piezoelectric torsional actuator
Ferroelectrics, 1994Piezoelectric torsional actuators have been developed from single ceramic cylindrical bodies using PZT based high d constant piezoelectric ceramics. The actuator geometry is able to produce rotational motion directly by DC voltage control without conventional complex conversion from XY direction motions.

Internal electrode piezoelectric ceramic actuator
Ferroelectrics, 1983An internal electrode multilayer piezoelectric ceramic actuator element has been investigated. An individual internal electrode has the same area as the element cross section area. It has no piezoelectric inactive part, so that it shows strain/field characteristics similar to plain piezoelectric ceramics. It can be driven by a relatively low voltage
