Piezoelectric multilayer actuator life test

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2011
Potential NASA optical missions such as the Space Interferometer Mission require actuators for precision positioning to accuracies of the order of nanometers. Commercially available multilayer piezoelectric stack actuators are being considered for driving these precision mirror positioning mechanisms. These mechanisms have potential mission operational

High-Precision Tracking of Piezoelectric Actuator Using Iterative Learning Control and Direct Inverse Compensation of Hysteresis

IEEE transactions on industrial electronics (1982. Print), 2019
Rate-dependent hysteretic nonlinearity, which is an inherent characteristic of piezoelectric actuators (PEAs), causes a significant challenge in precise motion control of piezoelectric nanopositioning stages.

Application of piezoelectric actuator to simplified haptic feedback system

, 2020
The lack of haptic feedback in minimally invasive surgery results in the dependence on high-resolution images. This study used a simplified working abstraction of a haptic feedback system, including a master manipulator, a console table, a slave indenter,

Analysis of Beams with Piezoelectric Actuators

Applied Mathematics and Mechanics, 2001
Based on the two-dimensional constitutive relationships of the piezoelectric material, an analytical solution for an intelligent beam excited by a pair of piezoelectric actuators is derived. With the solution the force and moment generated by two piezoelectric actuators and a pair of piezoelectric actuator/sensor are obtained.

Piezoelectric actuators in micropositioning

Engineering Science & Education Journal, 2001
Micromachines can be built only with the aid of other machines that have micropositioning abilities. Fast and precise positioning devices are needed to increase reliability and speed in the production of the miniaturized devices. Intensive research effort has been devoted to developing new technologies for actuators and sensors.

Piezoelectric membrane actuator design

2011 12th Intl. Conf. on Thermal, Mechanical & Multi-Physics Simulation and Experiments in Microelectronics and Microsystems, 2011
This paper presents the study of piezoelectric actuators. After the description of simulated actuators and simulation conditions, results will be discussed to define the best actuator design in terms of membrane displacement and compactness. The actuator behaviour under temperature variation is also checked.

Development of a Novel Two-DOF Pointing Mechanism Using a Bending–Bending Hybrid Piezoelectric Actuator

IEEE transactions on industrial electronics (1982. Print), 2019
A novel two-DOF pointing mechanism using a bending–bending hybrid piezoelectric actuator was proposed. The pointing mechanism realized rotary motions around two orthogonal axes by single actuator based on the inertial driving principle.
