A smart device that can dive or surface in aqueous medium has been developed by combining a pH‐responsive surface with acid‐responsive magnesium. The diving–surfacing cycles can be used to convert chemical energy into electricity. During the diving‐surfacing motion, the smart device cuts magnetic flux lines and produces a current, demonstrating that motional energy can be realized by consuming chemical energy of magnesium, thus producing electricity.
