Complaint micro grippers for medical applications need to be precise, automated in a smooth manner performing painless surgery to the patient. In this paper design of the grippers and force amplification are presented. First, the benefits of the design of compliant micro grippers by force amplification are listed out second, the flexure used grippers are presented third, the sensor-based complaint micro grippers are discussed fourth, actuator based compliant microgripper is presented. Finally, compliance of the gripper is validated by comparison of the various cross-sectional dimension of flexure objects and the current trend in the fabrication of complaint micro gripper's technology is summarized.
