纳米摩擦电发电机（TENG）通过接触起电和静电感应将机械能转化为电能。单摩擦表面纳米发电机（STENG）由于可以将手指作为一个摩擦表面进行接触起电，拓展了潜在的应用领域。在这项工作中，一个完全灵活的STENG已被制成，由聚二甲基硅氧烷（PDMS）与微纳米结构在其观察侧和一个灵活的电极在其反面。采用飞秒激光烧蚀技术在聚二甲基硅氧烷（PDMS）表面制备微纳结构，并将银纳米线（Ag NWs）嵌入PDMS中作为柔性感应电极。已经证明，能量转换效率大大提高，因为存在的微纳米结构的PDMS。进一步证实了STENG的作用机理。由于电极和PDMS具有完全柔性的特性，STENG可以很好地粘附在任何物体上，例如通过胶带粘附在衣服上。
Triboelectric nanogenerator(TENG) can convert mechanical energy to electrical energy through contact electrification and electrostatic induction. Single-friction-surface triboelectric nanogenerator(STENG) extends potential application because a finger can be used as one friction surface in the contact electrification. In this work, a fully flexible STENG has been made, consisting of polydimethylsiloxane(PDMS) with micro-nano structures on its observe side and a flexible electrode on its reverse side. The femtosecond laser ablation was introduced to make micro-nano structures on PDMS and Ag nanowires(Ag NWs) were embedded in PDMS to serve as flexible induction electrode. It has been demonstrated that the energy conversion efficiency increases greatly because of the existing micro-nano structures on PDMS. Further, the mechanism of STENG was proved. Owing to the fully flexible characteristics in both the electrode and PDMS, STENG works well when it is adhered on any subject, for example, on clothes by tape.
