In article number 1903379, Ahmed Mourran and co‐workers fabricate a spiral‐shaped microgel rotor that operates in the low Reynolds number regime. Light induces non‐equilibrium actuation of the hydrogel ribbon, which provides the necessary non‐reciprocal deformations to drive the rotor. The rotational motion is tunable by the modulation of the light.
