In light of the crucial role marine ecosystems and escalating environmental conservation challenges, it is essential to conduct monitoring help implement targeted protection measures efficiently. Energy harvesting technologies, particularly triboelectric nanogenerators (TENGs), have great potential for prolonging lifespan enhancing reliability sensors in remote areas. However, high internal resistance, low current, friction-induced abrasion issues TENGs limit their performance practical applications. This work presents a rolling mode nanogenerator that utilizes multi-tunnel grating electrodes opposite-charge-enhancement mechanism harvest wave energy The device achieves significant instantaneous root mean square power density 185.4 W/(m
