A Piezoelectric MEMS Microgripper for Arbitrary XY Trajectory [PDF]

open access: yesMicromachines, 2022
In this paper, a piezoelectric microgripper for arbitrary 2D trajectory is proposed. The desired trajectory of the specimen under consideration was obtained by the deformability of a structure consisting of 16 straight beams and 12 C-structures.

Z-Shaped Electrothermal Microgripper Based on Novel Asymmetric Actuator [PDF]

open access: yesMicromachines, 2022
Based on a V-shaped microactuator with a pair of beams, modifications were made to the length and width of a microactuator to observe the effects. A theoretical approach and numerical characterization of the modified microactuator were performed.
