摘要

循环经济结合了生物可降解材料的再利用、再制造和现代化，用于绿色能源的应用。本研究比较了低温脆化生物废弃物天然人发（LN2-hair）的摩擦学性能与利用室温处理的人发（RT-hair）开发的摩擦学性能。形态学和电学表征表明，与RT毛发（~ 700 μm）相比，具有微断裂和多孔结构（~ 1 μm）的ln2毛发颗粒的平均尺寸为~ 300 μm。ln2 -毛发TENG的功率密度（~ 327 mWm−2）大于同等大小的rt -毛发TENG (~ 141 mWm−2)，显示出数千次攻丝循环的稳定性。

Sustainable micro energy harvesting using cryogenically processed bio-waste natural human hair as a triboelectric material

Circular economy incorporates reuse, remanufacturing, and modernization of biodegradable materials to be used in green energy applications. This study compares the triboelectric properties of cryogenically embrittled bio-waste natural human hair (LN2-hair) based TENG with a TENG developed using human hair processed at room temperature (RT-hair). Morphological and electrical characterization showed that the LN2-hair particles with microfractures and porous structures (∼1 μm) had an average size of ∼300 μm compared to that of RT hair (∼700 μm). The power density (∼327 mWm⁻²) of LN2-hair TENG was larger than an equally-sized RT-hair TENG (∼141 mWm⁻²), demonstrating stability for thousands of tapping cycles.
