Segmented gripper jaw with markers (red) to measure the gripping force
The handling and exact controlling of microgrippers requires high precision. The measuring devices used to date are characterized by great manufacturing effort and only allow a limited selection of materials to be used. PTB's concept simplifies the measurement of the gripping force: the grippers are segmented and interconnected by means of spring elements to reduce their stiffness. Markers are applied to both segments; they are then optically recorded by a camera. This allows the gripping force to be measured accurately without applying strain gauges or microelectromechanical systems (MEMS). (Technology Offer 0436)
