These actuators are 'low voltage piezo actuators'. N ominal operation voltage is 0 to 150 V.
They consist of stacked piezoelectric plates which are connected electrically parallel.

Additional piezo life testing results are available for download here. P iezo stack actuators are available in a broad range of shapes and sizes from 1 x 1 up to 25 x 25 mm 2 are available. Chips and discrete stacks with through-holes, shear chips, stacks with attached strain gauges, and bimorph bending actuators are available, as well as piezo ring chips and ring. PICMA® actuators are space qualified and were submittet 100 billion cycles of life testing at NASA's JPL. Piezo stack actuation is a solid-state technology, which enables high technology solutions. Our selection of piezo chips and stacks includes co-fired chips, co-fired stacks, and discrete stacks, as well as stacks with strain-gauges for closed-loop operation. PI's piezo ceramic design and manufacturing division - PI Ceramic - provides the capability and flexibility to offer highly engineered custom sub-assemblies at a very attractive price.ġ00 Billion Cycles of Life Testing, Space Qualified PI's award-winning and MARS-Rover-Proven PICMA® ceramic-encapsulated co-fired piezo stacks are polymer-free and combine superior performance with extremely long lifetime. PI's discrete actuators and the PICMA cofired stacks are available for operating temperatures up to 200 deg C. Applications for piezo actuators include fiber modulation for communications, precise positioning devices, proportioning valves, electrical switches, micro. High Curie / Operating Temperatures: PI's piezo ceramic formulation boasts a high Curie temperature for a wide operating temperature range.
For more information on the differences between piezo motors and actuators and their applications watch the video below, refer to the piezo motion tutorial or just contact a PI applications engineer for help. Maximum displacement and force were tested as 36.9 m and 669.5 N under different frequency AC. It is important to understand the principles to pick the best type for an application. PiezoDirects piezoelectric stack actuators provide precise and powerful actuation for a wide range of industrial and scientific applications. Test systems of piezoelectric stack actuator with and without mechanical load were designed.
