Lightweight, compact, flexible hybrid electronics are used to precisely release ethanol to achieve controllable propulsion, smart sensing, and wireless communication functions. The PM-motor utilizes the surface tension gradient generated by the ethanol, which is released from leaf-inspired veins and improves fuel efficiency by 3.5 times when compared with traditional Marangoni effect-propelled robots. As a result, the device’s endurance is up to ∼226 s for a navigation distance of ∼5 m with just 1.2 mL ethanol. Benefiting from the leaf-like shape and negligible noise production, the S-aquabots can also blend well with their surroundings. Autonomous response capability is demonstrated by guiding an S-aquabot with laser spots to complete a butterfly-shaped trajectory.
