As one of the most important renewable energy sources, ocean wave energy is inexhaustible and has broad development potential. Herein, we propose a novel spring-assisted triboelectric nanogenerator (SS-TENG) for harvesting shore-based wave energy. SS-TENG realizes ocean wave energy conversion through the “wave–floating platform–spring” transmission structure, which avoids direct contact with seawater and minimizes the damage to the power generation module caused by a corrosive environment. The output performance of SS-TENG is significantly enhanced in two ways. First, by utilizing the elastic potential energy released by the spring, the instantaneous contact speed between the electrode and dielectric layer is boosted, and the peak current output IP by a single TENG unit increases from 7.36 to 12.12 μA. Second, benefiting from the synchronous movement of each TENG unit, the TENGs can be connected in parallel to achieve the linear increase of IP from 12.12 μA for a single unit to 43.86 μA for four units. SS-TENG can provide sufficient energy to drive a digital calculator and up to 160 high luminosity LEDs, verifying its superior performance. The proposed design has the merits of modest structure, low production cost, excellent output performance, and long-term stability, and is expected to inspire the development of shore-based wave energy generators and self-sufficient ocean sensors. |
