Summary: Developing clean and renewable energy sources is important for reducing carbon emissions and achieving carbon neutrality. This study demonstrates a hyperelastic network of wheel-structured triboelectric nanogenerators (WS-TENGs) that efficiently harvest low-frequency and small-amplitude wave energy. The external blades on the TENG allow for a tighter interaction with the waves, leading to continuous agitation and enhanced energy harvesting. The hyperelastic networking structure further intensifies the device's roll and enables large-scale network formation. The study provides a new driving paradigm for enhancing blue energy utilization based on TENGs.

Summary: A new triboelectric-electromagnetic hybrid nanogenerator (TEHG) has been developed, which combines a soft ball-based triboelectric nanogenerator (SB-TENG) and an electromagnetic generator (EMG) for efficient energy harvesting from low-frequency water waves. The critical parameters affecting the energy harvesting performance of the SB-TENG have been investigated, including the type of filled liquids, silicone shell thickness, number of layers, and added soft balls. Under an operating frequency of 1 Hz, the SB-TENG and EMG can reach a maximum output peak power of 0.5 and 8.5 mW, respectively. This study not only presents a new design and approach to enhance the output performance of TENGs, but also demonstrates the potential of a self-powered water-sensing system driven by low-frequency water waves.
