Microscope images of micro-gears controlled by optical ring spanners with ring thicknesses of a 0 μm, b 10 μm, c 30 μm, and d 60 μm. Plots of maximum e angular velocity of rotating micro-gears and f linear velocity of translating micro-gears as a function of OET bias voltage for optical ring spanners with ring thicknesses of 0 μm (black squares), 10 μm (red circles), 30 μm (blue triangles), and 60 μm (green inverted triangles). The frequency of the OET bias was set to 10 kHz. Error bars represent ±1 SD from five measurements for each condition.
