Description
Summary:[Display omitted] Flexible triboelectric generators present a wide range of prospective applications owing to their small size, light weight, and wearability; in addition, they can convert external mechanical energy into electrical energy to provide an energy supply for wearable electronic products. In this study, a wearable textile triboelectric generator was developed by weaving polyurethane (PU) nanofiber core-spun yarn and Si3N4-electret-doped polyvinylidene fluoride (PVDF) nanofiber core-spun yarn into a double-layer fabric. Within the double-layer fabric, one layer was Si3N4-doped PVDF (denoted as Si3N4@PVDF) nanofiber fabric, and the other was PU nanofiber fabric. When subjected to an external mechanical force, PU nanofiber fabric and Si3N4@PVDF nanofiber fabric came into contact and were able to convert external mechanical energy into electrical energy. The most notable instantaneous electrical performance of this triboelectric nanogenerator was open circuit voltage of 71 V, short-circuit current of 0.7 μA, and output power of 56 μW. Additionally, the wearable textile triboelectric generator exhibited superior washability, stability, and cycle durability. More significantly, it was capable of driving some low-consumption electronic products, including capacitors, LED bulbs, and digital meters, thereby exhibiting a strong potential for flexible self-powered electronic devices and intelligent textiles.
