Due to the simple installation and convenient maintenance, floating water wave energy harvesting devices have significant economic advantages. Mass power density is most important index evaluate advancement of devices. Herein, a self-adaptive rotating triboelectric nanogenerator (SR-TENG) with compound pendulum functional gear-set provided for harvesting. First, structure low center gravity high moment inertia obtained by geometric design mechanical study. Besides, compared previous one-way clutch, SR-TENG can harvest twice kinetic utilization through gear-set. Importantly, depending on design, obtains average mass 45.18 mW kg-1 under frequency driving conditions, which about 10 times reference electromagnetic generator similar size. This result shows that has advantage in small These findings provide an example

Omnidirectional water wave energy harvesting by a spherical triboelectric nanogenerator with sliced-pizza-shaped electrodes

Cell Reports Physical Science, Год журнала: 2024, Номер 5(5), С. 101933 - 101933

Опубликована: Апрель 18, 2024

Ocean waves contain abundant renewable kinetic energy, but harnessing their power is difficult due to low frequency and erratic nature. Here, we report a spherical triboelectric nanogenerator featuring multilayer "sliced-pizza-shaped" electrodes (SP-TENG) efficiently harness omnidirectional wave energy. Unlike conventional TENGs that either convert motion from single direction or compromise energy-harvesting efficiency capture multi-directional our SP-TENG not only effectively harnesses energy also maximizes electric output by fully utilizing the device's internal space. Moreover, using polypropylene fur as tribo-material further increases charge enhancing inter-material contact efficiency. The captures all directions, achieving peak density of 13 W/m3 2.4 mC/m3 at 0.6 Hz frequency. This study presents practical efficient approach for harvesting high-entropy blue on large scale.
