Micro Motion Amplifiers for Compact Out-of-Plane Actuation. [PDF]

Micromachines (Basel), 2018
Small-scale, out-of-plane actuators can enable tactile interfaces; however, achieving sufficient actuator force and displacement can require larger actuators. In this work, 2-mm2 out-of-plane microactuators were created, and were demonstrated to output up to 6.3 µm of displacement and 16 mN of blocking force at 170 V.

Thermally induced micro-motion by inflection in optical potential. [PDF]

Sci Rep, 2017
ABSTRACTRecent technological progress in a precise control of optically trapped objects allows much broader ventures to unexplored territory of thermal motion in non-linear potentials. In this work, we exploit an experimental set-up of holographic optical tweezers to experimentally investigate Brownian motion of a micro-particle near the inflection ...
