Biomimetic cross‐linked polymersomes that exhibit a self‐beating motion without any on–off switching are developed. The polymersomes are made from a well‐defined synthetic thermoresponsive diblock copolymer, and the thermoresponsive segment includes ruthenium catalysts for the oscillatory chemical reaction and vinylidene groups to cross‐link the polymersomes. Autonomous volume and shape oscillations of the cross‐linked polymersomes are realized following redox changes of the catalysts.
