The static and dynamic response of SU-8 electrothermal microgrippers of varying thickness
Grippers of different thicknesses have been fabricated and tested. Thermal camera imaging has been used to confirm the gripper temperature profile. Effect of voltage and current on settling time and arm movement has been measured. A COMSOL Multiphysics model matches the findings of the experimental results.
