Light-weight and compact precision piezo actuators and grippers from PI USA present excessive pace and nanometer decision in a small bundle.
Auburn, MA – The piezoelectric impact immediately converts electrical power into mechanical movement. PI makes use of this impact for prime precision, solid-state based mostly actuators and grippers. Embedding a piezoceramic stack in a flexure-based association can enhance the movement vary of the piezo actuator whereas offering safety, precision steering, and a mounting interface on the similar time. PI’s movement amplified piezo actuators are power environment friendly and supply millisecond quick response and nearly limitless positional decision.

In comparison with conventional piezo stack actuators, amplified piezo actuators present prolonged movement ranges and will be simply built-in in OEM functions, resembling precision instrumentation, grippers for micro-optics and medical units, excessive pace valves, nano-dosing and pumping, fiber-optic alignment, nanopositioning, nano-dispensing, biotechnology, microfluidics, medical-devices, microscopy, and life-sciences.
On the coronary heart of all PI motion-amplified piezo actuators is a PICMA® multilayer piezo ceramic ingredient, of the identical patented building as those used on the Mars rover for his or her excessive reliability and lifelong past 100 billion cycles. PI’s patented, ceramic insulated multi-layer PICMA® piezoelectric actuators are additionally 100% vacuum appropriate and may work in a large temperature vary.
Movement amplified piezo actuators with high-stiffness designs enable for prime load capability and insensitivity to shock and vibration. Built-in suggestions sensors allow extremely linear and repeatable movement or pressure management, when operated with a PI’s closed-loop piezo-controllers.
Why Ultrafast Piezo Know-how?
Piezoelectric movement parts are extremely valued for his or her quick response occasions, able to dynamic actions at frequencies reaching a number of kHz and delivering movement decision all the way down to the sub-nanometer degree. Their operation is pushed by molecular results, with a solid-state design that eliminates conventional shifting components, bearings, or gears, making them maintenance-free. This benefit arises from the inverse piezoelectric impact of their crystalline construction, which operates with out friction-inducing parts. Moreover, piezo actuators are exceptionally energy-efficient, as they draw no energy when idle, or holding a gentle place. These qualities make them versatile for numerous functions, resembling in course of know-how, the place they permit speedy dosing cycles with finely adjustable, exact movement management important for dosing accuracy.
