Abstract Harnessing energy from underwater bubbles has garnered significant attention, particularly for powering off‐grid circuitry. However, the efficiency of bubble‐driven liquid‐solid interface charge transfer remains low. This research unveils a phenomenon: accelerated bubble slippage enhances interfacial transfer. Building upon this discovery, pulse bubble‐based power generation technique is proposed, achieving an density 24.2 mJ L −1 generated by pulsed bubbles. The crux lies in precise control impact velocity. By meticulously regulating kinetic bubbles, accumulated potential multiple small converted into instantaneous energy. A typical controlled within 72 ms timeframe, unleashing surge that can directly illuminate 400 light‐emitting diodes. approach represents groundbreaking advancement harvesting technology, dramatically expanding its applications.
