This paper presents simulation and measurement results characterizing a novel design of an electro-thermally actuated micro-gripper for micro-particles manipulation. The gripper structure consists of a comb-like, high aspect ratio silicon frame with an integrated aluminum heater on top. The comb-structure trenches are filled with SU8, a photo-patternable polymer material. The gripper fabrication process makes use of standard semiconductor processing steps and materials. The presented gripper features a large maximum total jaw displacement of 68 µm at a driving voltage of 4 V and a total power consumption of 93,8 mW. the simulated force capability of the device is 0.57 mN per µm jaw displacement. Key Words: Bimorph actuator, SU8 polymer, micro-gripper, FE simulation, electro-thermal-elastic coupling.@en
