Jul 10, 2013 · A flexure is a solid, typically monolithic device that introduces displacement as a result of elastic deformation of the material. Unlike conventional bearings or actuators that produce motion courtesy of rolling or sliding surfaces, …

This piezo actuator tutorial covers how piezo actuators work, the major application benefits, flexure-guided actuator properties and characteristics, frame architectures, travel, force, frequency, and how to select a piezo actuator for your application.

A flexure-guided piezo stage incorporates a stacked piezo actuator with mechanical linkages, similar to hinges, that amplify the actuator’s motion and provide guidance for the attached load.

Flexure-guided and motion-amplified actuators provide convenience and performance for the OEM designer. Piezo motors expand the motion range. Piezo actuators, a special form of electro-ceramics, are the gold standard when it comes to precision, speed, and force in a small package.

Flexures allow motions with extremely high path accuracy. To compensate for height or transversal offset, PI has developed special multi-link flexure guides. These guiding systems, which are used in most nanopositioning systems from PI, allow a flatness and straightness in the subnanometer or microradian range.

PI’s high-displacement series of motion amplified piezoelectric actuators integrate a low voltage, multi-layer piezoceramic stack in a flexure guided housing assembly. The flexure provides guiding, preload, and doubles as a motion amplifier.

Flexure-guided and motion-amplified actuators and positioning stages provide convenience and performance for the OEM designer and scientist. Piezo actuators, a special form of electro-ceramics, are the gold standard when it comes to precision, speed, and force in a small package.

In this article, flexure variable stiffness actuators (F-VSAs), which combine kinematic transmission, elasticity, and stiffness modulation via a network of folding patterns using flexure hinges, are presented.

Apr 8, 2024 · Flexures are leveraged to make quantitative comparisons of force, work, and power outputs in muscle actuators, driving us to discover a new observation of frequency-dependent fatigue in muscle, and also develop a novel method for tuning muscle contractile dynamics in a frequency-independent manner.

Piezo Flexure-Guided Actuators (Flextensional Actuators) provide nanometer precison, fast response and travel ranges to 1000m and more. They are completely frictionless don't require lubricants or maintenance and have lifetimes of several billion cycles.
