Technological advancement in precision industries generates enthusiasm in engineers and scientists. Microgripper is an elementary device in precision manipulation of micro-objects. For precision manipulation of micro devices or micro assembly of components, the design of microgripper is a challenging task. Design of mechanism influenced micro devices are required new methodology. In this research work, an attempt has been made to develop a new compliant mechanism design of microgripper with force sensing jaw. Topology optimization technique has been used to derive the conceptual design of mechanism of microgripper. This conceptual design is post-processed, that is, the flexure hinges and smoothened edges are introduced in the senseless regions suitably to achieve the final design. Gripping force acting on the object is calculated introducing a cantilever jaw. Deflection of cantilever jaw is directly proportional to the gripping force acting on the object. A detailed study of the flexible cantilever gripping device and its behavior with various parameters of circular flexure hinges is performed and the gripping force is measured through finite element software ANSYS Workbench. First natural frequency of the micro gripper and out of plane sagging due to the self weight of the micro gripper is measured to ensure the effectiveness of design.
