Summary: In this study, PVDF-based triboelectric nanogenerators (TENGs) were prepared by adding aromatic hyperbranched polyester (Ar.HBP-3) as a filler. The PVDF-Ar.HBP-3/PU-based TENG showed better triboelectric performance than a PVDF/PU pair. Among the different wt.% of Ar.HBP-3, the sample with 10 wt.% exhibited the highest output performance with an open-circuit voltage of 107 V, which is 10 times higher than that of neat PVDF. Additionally, the TENG was effective in measuring human motion. This study presents a simpler technique for producing high-performance TENGs using PVDF morphological alteration, which has great potential for mechanical energy harvesting and powering wearable and portable electronic devices.

Summary: In this study, the performance outputs of triboelectric nanogenerators (TENGs) were enhanced using polyvinylidene fluoride (PVDF)/fullerene (C-60) composite nanofibers (NFs). It was found that the incorporation of C-60 into the PVDF matrix improved the output power of the TENG devices, but an excessive amount of C-60 resulted in a decrease in power. The increase in C-60 content in the PVDF matrix enhanced the TENG performance by improving trap charge ability and electronegativity, and the output power was sufficient to operate a display device.

Summary: This study presents a self-healing triboelectric nanogenerator (TENG) fabricated using self-healing polyimide (PI) for energy harvesting and motion sensing. The PI-based TENGs exhibited excellent intrinsic self-healing properties, attributed to dynamic disulfide bond exchange and flexible PDMS fragments in the PI backbone. The output performance of the TENG was significantly improved due to CF3 electron-absorbing groups and siloxane fragments in the PI backbone. Practical applications of self-healing PI-based TENGs, including energy harvesting for commercial electronic devices and joint motion sensing, were demonstrated.

Summary: A highly adaptive hybrid nanogenerator based on triboelectric nanogenerator and electromagnetic generator is proposed, which can scavenge wind energy and ocean current energy. The peak power of the hybrid nanogenerator can reach 449.74 mW, capable of recharging a 50 mAh-3.7 V Lithium battery. Additionally, the hybrid nanogenerator can serve as a flow velocity sensor due to the linear relationship between the voltage frequency of the triboelectric nanogenerator and the rotation speed. A fully self-powered marine wireless sensor node based on the hybrid nanogenerator and management circuit is fabricated, demonstrating its potential applications in nearshore, offshore, and underwater scenarios.
