Abstract. A new piezoelectric gripper is presented. The device operates in a self-sensing mode without any additional sensors, and is able to perform micro-positioning of small details. The micro-positioning and selfsensing functions were examined both theoretically and experimentally. The self-sufficient grip works reliably and safely and is shown to be appropriate for micro assembling.
Keywords: piezoelectric grip, bimorph, micro-positioning, sensing, experimental stand.
