Abstract |
By leveraging nature's ingenuity and adopting a circular economy approach, bio-inspired triboelectric nanogenerators (TENGs) can not only generate clean electricity but also contribute to environmental stewardship and resource conservation. Herein, a novel approach to developing bio-inspired TENGs utilizing recycled natural fibres sourced from agricultural waste is reported. The potential of various natural fibres, including coco peat, sugarcane husk, pistachio shell, and flax shive, for integration into TENG applications is investigated. Natural fibres-based TENGs (NF-TENGs) comprising polyvinyl alcohol and the aforementioned agro-waste composites are fabricated using a straightforward solution casting technique. Structural, elemental, and interaction analyses of these fibres are systematically conducted using analytical techniques such as Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy, and Fourier Transform Infrared spectroscopy. Electrical characterizations, encompassing voltage, current, and determination of optimal load resistance, along with device stability assessments, are performed on the NF-TENGs. Furthermore, the optimized NF-TENG, composed of flax-seed husk, is demonstrated for powering small-scale electronics including charging electrolytic capacitors, LEDs, and functioning as a self-powered biomechanical sensor. This research marks a significant advancement in sustainable energy technologies by harnessing the latent potential of agricultural waste-derived natural fibres. |
