Piezo-Engineering for Highly-Precise Position and Strong Force

Piezo stack actuators are available in a broad range of shapes and sizes from 1 x 1 up to 25 x 25 mm2 are available. They consist of stacked piezoelectric plates which are connected electrically parallel.

 

Nominal operation voltage is 0 to 150 V. These actuators are "low voltage piezo actuators". The actuators also allow semi-bipolar operation with an extended driver voltage range of up to-30 V to 150 V. This method of operation  result in significantly larger displacement.  

Bare stacks are perfect for integration into custom mechanism. The stacks have generally a small size when they are compared with other actuator types like hydraulic cylinders at same force. Alos interfacing is extremely simple. The piezo stacks are cuboid and have two electrical wires to control the element. Encased actuators with pre-stress mechanism are ideal solution for robust system integration.  

Piezo actuators can be operated in extreme environments. Adaptations are possible for operation in cryogenic temperature, in vacuum, and in exotic environment such as high-g field or vibration.

Standard piezo stack program

Customized Piezos. Piezo stacks with rectangular  as well as cylindrical shape are available. Ring-shaped stacks are choices for optical applications. Hole-through stacks and special designs are available on request. Actuator with thick coating (green colored) are also available on request.

Metal sealed type
 are hermetically encasing the piezo stack which is sensitive to excessive humidity.

Metal casing is a perfect solution for difficult environments such as humid workplaces when the relative humidity is higher than 60%, oil spray or dew condition. The piezo stack is protected in a stainless steel package. A broad range of actuators are available for all sizes and with  different mounting brackets (female thread type or flange type).
