AUBURN, Mass., Aug. 24, 2012 — PI (Physik Instrumente L.P.) is offering a line of co-fired multilayer piezo bimorph actuators that achieve a mechanical amplification effect via different layers expanding at different rates. They are monolithic, and all layers are produced in one step.
They achieve long travel ranges with motion to 2 mm and nanometer resolution. Response times are in the millisecond range, important for fast switching and scanning applications. They provide good mechanical stability and low operating voltage and can be operated at a temperature of 150 °C.
Applications include pneumatic valves, fast optical switches, beam deflection, micropositioning acceleration sensors, medical device engineering, semiconductor manufacturing, aerospace, bionanotechnology and automotive.
The actuators can be factory-equipped with position feedback sensors for closed-loop operation. Controllers, OEM driver electronics and piezo power supplies are also available.
They come in a variety of standard and custom shapes, from rectangular stripes to triangles to circular disks with an optional aperture. Compact versions of a few millimeters can be produced.
