As an endeffector in the micromanipulation system, the compliant microgripper is of great importance in micro manipulations. A pseudorigidbody model of a novel compliant microgripper was established, and the kinematic equations were formulated based on developing and analyzing the pseudorigidbody model by using the principle of virtual work. The relationship between input and output displacements as well as the relationship between input force and output displacement were then derived. The analytical model was verified via 3D simulations by using ANSYS software. The simulation results were compared with the theoretical results and the error was less than 28% within the required range. Finally, the compliant microgripper was fabricated and the micromanipulation system was established. Then displacement experimental tests were conducted by using the fabricated microgripper. Experimental data was compared with both analytical and simulation results to further validate the accuracy of the analytical model. It was proved that the new microgripper displacement can get 8965μm with 1V voltage applied. And the error between the analytical results and experimental data was not more than 32% in useable range. The displacement characteristics were got by the pseudorigidbody model and verified by the simulation results and the experiments data. The microgripper can manipulate suitable subjects with size within 500μm to 679μm from the analysis results.
