Abstract:
A microtool for manipulating or positioning a microcomponent, comprising:a gripper structure having a first arm a second arm, and at least one gripping surface, the gripper structure positioning at least one microcomponent into a predetermined position using the at least one gripping surface; a first actuator structure moving the gripper structure, the actuator structure including an interdigital capacitor, the interdigital capacitor including an anchored comb structure and a eg comb structure of a leg; and at least one arrangement producing at east a temporary acceleration of at least one of the first arm and the second arm such that a first force of inertia is greater than a second force of adhesion, the first force of inertia being generated by an inertial mass of the at least one microcomponent and the at least temporary acceleration, the second force of adhesion acting between the at least one microcomponent and the at least one gripping surface.
