Abstract This study focuses on analysis of arbitrarily modified architecture of piezoelectric microgripper for unmanned aerial vehicle application. The piezoelectric analysis is carried out in COMSOL MULTIPHYSICS 4.2 software. The existing piezoelectric and structurally modified piezoelectric microgripper are modelled and analysed. Different materials such as silicon, polysilicon and silicon dioxide are taken into consideration for analysis among which silicon dioxide gives better result when compared to other materials. The total displacements of existing and modified micro grippers are numerically analysed and the modified microgripper gives better result when compared to existing microgripper. © 2018 Elsevier Ltd.

Introduction Recently, the demands of micromanipulation in terms of precision and efficiency have been growing with the development of biological engineering and microelectronics industry. In micromanipulation, the microgripper plays the major role in handling components [1-3].As the development of parallel-plate electrostatic micro gripper, some micro machined gripper .They use different actuation types: electrostatic, piezoelectric, suction, SMA and thermal bimorph effect [4-6]. Use of piezoelectric actuation has several advantages such as zero backlashes; fast response, small volume and large output force [7-9]. Some of the effective parameters are material specification, displacement amplification factor, gripping range, aspect ratio, number of degree of freedom and micro actuator specifications on the performance and designing of the micro grippers are reviewed.[10] * Corresponding author.
