This paper presents a novel micro-gripper design with the dual functions of manipulation and force sensing. The device consists of two parallel plates, each mounted on torsion bars, which can be made to rotate towards or away from each other by use of a pneumatically- or hydraulically- Actuated balloon. The plates can be conveniently fabricated using photo-etching and the design allows for a range of ratios between actuation pressure and tip opening displacement and/or force. The elastic gripping tips can be designed to provide sufficient compliance that their strain can be used to monitor and/or control the gripping force.
