From: Design of a large-range rotary microgripper with freeform geometries using a genetic algorithm
a Images of designs CB7-D2 and SB7 under an actuation voltage of 47.5 V. Comparison of radial deflection Rm of the rotary comb actuators for different microgripper designs. (1) No apparent Rm in the microgripper design SB7 under an actuation voltage of 40 V. (2) Small Rm in the microgripper design CB7-D2 under an actuation voltage of 40 V. (3) Large Rm in the microgripper design CB7-D1 under an actuation voltage of 40 V. (4) Pull-in of the microgripper design CB7-D1 under an actuation voltage of 41 V. b Gripping a human hair with a diameter of 77 μm using microgripper design CB7-D2 (1) before gripping and (2) after gripping
