Energy from mechanical vibrations is prevalent in the ambient, which can be effectively harvested using triboelectric generators. However, the efficiency of the harvesters is limited by the narrow bandwidth. Herein, we propose combining Vibro-impact and magnetic nonlinearity for Polydimethylsiloxane-based triboelectric energy harvesters to extend the operation bandwidth and enhance the efficiency of the traditional triboelectric harvesters. Our harvester design consists of a cantilever beam with a tip magnet facing another fixed magnet at the same polarity, inducing a nonlinear magnetic repulsive force. The lower surface of the tip magnet acts as an upper electrode of a triboelectric harvester, while the lower electrode with attached Polydimethylsiloxane (PDMS) insulator. Under the effect of base excitation, the system can vibrate in monostable or bistable oscillations by varying the distance between the two magnets, causing an impact on the triboelectric electrodes, and an alternative electrical signal is generated at a wide range of frequencies. The harvester's static and dynamic behaviors are investigated theoretically and experimentally validated at different separation distances between the two magnets. We achieved higher bandwidth by combining Vibro-impact with magnetic nonlinearity, and triboelectric energy harvesters show promising applications for future wireless sensor networks at wider operation frequency bandwidth.

“…investigated the effects of wind speed, length and thickness of the film, and spacing between the upper and lower of two flat electrodes on the performance of the TENG. The results show that choosing appropriate structural parameters can effectively improve the performance of the energy harvester and reduce the cut-in wind speed ( Xia et al., 2021 ). Lin et al.…”

“…It is generally considered that the electrostatic charge generated by friction is a kind of wasted electrical energy [ 3 ]. In 2012, Professor Zhonglin Wang invented triboelectric nanogenerator (TENG) technology based on triboelectric and electrostatic induction coupling [ 4 , 5 , 6 , 7 , 8 ], which can collect various forms of energy and convert it into electrical energy, such as wind energy [ 9 , 10 , 11 , 12 , 13 ], ocean energy [ 14 , 15 , 16 ], vibration energy [ 17 , 18 , 19 ], human movement energy [ 20 , 21 , 22 ]. Compared with the traditional electromagnetic induction power generation technology, TENG has the advantages of being light weight and having a high-power generation voltage, small size, flexibility and shape flexibility, and high compatibility [ 23 , 24 , 25 , 26 ], and has received extensive attention from researchers.…”

The sliding freestanding layer triboelectric nanogenerator (SF-TENG) is a sustainable power source that can convert mechanical energy from linear or rotating mechanical motion to electrical energy. This paper proposes a double-layer staggered chain teeth TENG. Comparing the staggered electrode TENG and the double-layer staggered electrode TENG, the output voltage difference is relatively small. The electrode of the TENG is designed to the shape of chain teeth, which proves that TENG can be combined with a zipper, and the best distance among chain teeth in the TENG is determined through experiments. Compared with traditional zippers, the double-layer staggered chain teeth TENG can generate electrical energy during the continuous pulling of the zipper. The double-layer staggered chain teeth TENG has good performance. When the external load is 20 MΩ, the maximum output power reaches 20.18 µW. After the rectification and transformation, the generated electricity can light up 30 LED lights or more, and can also supply power to electronic devices. Through the chain teeth array, the open circuit voltage and transfer charge generated by the zipper during the continuous pulling process are improved. The double-layer staggered chain teeth TENG has a good usage environment in life, and this work will provide valuable insights for the development of SF-TENG technology.
