a Independent control of two stepper micromotors in the same E-field. The micromotors are both driven by a rotating E-field with \(f_1 = 100\,{\mathrm{kHz}}\,{\mathrm{and}}\,f_2 = 1.49\,{\mathrm{Hz}}\,{\mathrm{at}}\,13\,{\mathrm{Vpp}}\). Digital light projecting (DLP) system projects light on each micromotor independently at an intensity of ~50 mW cm−2. b Rotation of a micromotor to designated angular positions like a stepper motor by stopping the rotation of the AC E-field at specific angle (f1 = 100 kHz, V = 10 Vpp, laser intensity = 127 mW cm−2), scale bar 10 μm. c Angle fluctuation around a designated angle at different voltages (frequency = 100 kHz). Probability density is fitted by normal distribution.
