The motion of a Picoactuator® piezoelectric crystal is highly linear and almost hysteresis-free. This allows highly repeatable bidrectional positioning, even without additional position metrology or closed-loop control. Therefore, the Picoactuator® technology is ideal for highly dynamic scanning with low electrical power consumption.
Picoactuator® piezo actuators can be configured as longitudinal or shear actuators, allowing the construction of particularly compact multi-axis actuators. The actuators are based on lead-free, single crystal material, which has a highly linear, hysteresis-free characteristic, but with small piezoelectric coefficients. The crystalline material allows for heights of up to 20 mm and maximum travel ranges of up to ±3 µm. The piezo voltage is -500 to +500 V.
