PICA Shear piezo actuators are extremely compact and allow sub-nanometer resolution, high-speed response times and high positioning forces. Piezo actuators in stacked design can be configured for shear displacement.
When combined with longitudinal actuators, particularly compact multi-axis piezo actuators can be assembled. A relatively large displacement combined with low electrical capacitance allows excellent dynamic properties while minimizing the electrical power consumption.
PICA Shear variants with inner hole feature a clear aperture, for example, for applying a pretension or for optical applications. Variants for cryogenic and UHV environments can be operated reliably at temperatures down to 4 K and UHV down to 10-9 hPa. The operating voltage is in the range from -250 to +250 V.
