Abstract: The strategy of linear compensation for nonlinear stiffness to flexibly adjust the degree of stiffness is widely applied in the field of vibration reduction but remains relatively uncommon ...

Abstract: This article presents an untethered self-moving *piezoelectric actuator (USPA) capable of producing the load-carriable, fast, and precise movement. Here, a pair of piezoelectric stack plates ...

PI Ceramic, a leader in piezoceramic innovation, has significantly shortened its lead times for its highly reliable PICMA ® Stack multilayer piezo actuators. Furthermore, a polymer-free, monolithic ...

Piezoelectric actuators (benders, stacks, chips, etc.) are excellent fast and precise means for generation and control of micro, nano, and even atomic scale movement on millisecond and faster ...

The piezoelectric effect directly converts electrical energy into mechanical motion. PI uses this effect for high precision, solid-state based actuators and grippers. Embedding a piezoceramic stack in ...

Lightweight and compact precision piezo actuators and grippers from PI USA provide high speed and nanometer resolution in a small package. Auburn, MA – The piezoelectric effect directly converts ...

A high-speed head positioner in a hard-disk track profiler; a sensitive tip/tilt planarization mechanism for a semiconductor wafer chuck; a dimensionally-stabilized laser cavity; an active ...
