The development and characteristics of microgripper is discussed. Actuation technologies of micro-mechanical cantilever are summarized, and formula for capacitance and electrostatic force involving edge-effect of comb- drive actuator are derived.
A comb-drive electrostatically actuated microgripper and its design process are described in detail. Electro-conductive fingers of gripper are connected to ground, in order to release the electric charges on the surface of fingers and grippin...
