MEMS based micro-grippers reveals excellent flexibility and adaptability in miniaturization devices in various engineering applications, such as micromanipulations, micro assemblies, etc... The actuating integrated micro-grippers are the subject of several multi physics analyses. Such analyses are used to study the micro grippers mechanical manipulation under a low power consumption. The studied micro-gripper consists of two gripping tips attached to two U-shaped actuators. The device is used to hold micro objects by deflecting its both arms under an applied DC voltage.
