Fire disaster is one of the most common hazards that threaten public safety and social development: how to improve the fire escape and rescue capacity remains a huge challenge. Here, a 3D honeycomb-structured woven fabric triboelectric nanogenerator (F-TENG) based on a flame-retardant wrapping yarn is developed. The wrapping yarn is fabricated through a continuous hollow spindle fancy twister technology, which is compatible with traditional textile production processes. The resulting 3D F-TENG can be used in smart carpets as a self-powered escape and rescue system that can precisely locate the survivor position and point out the escape route to timely assist victim search and rescuing. As interior decoration, the unique design of the honeycomb weaving structure endows the F-TENG fabric with an excellent noise-reduction ability. In addition, combining with its good machine washability, air permeability, flame-retardency, durability, and repeatability features, the 3D F-TENG may have great potential applications in fire rescue and wearable sensors as well as smart home decoration.
如何提高火灾逃生和救援能力仍然是一个巨大的挑战。在此，基于阻燃包覆纱线开发了一种三维蜂窝结构编织织物摩擦电纳米发电机（F-TENG）。包覆纱线通过连续空心锭花式捻线技术制造，该技术与传统纺织生产工艺兼容。由此产生的三维F-TENG可用于智能地毯，作为一种自供电逃生和救援系统，能够精确确定幸存者位置并指出逃生路线，以便及时协助受害者搜索和救援。作为室内装饰，蜂窝编织结构的独特设计赋予了F-TENG织物出色的降噪能力。此外，结合其良好的机洗性、透气性、阻燃性、耐用性和可重复性等特点，三维F-TENG在火灾救援、可穿戴传感器以及智能家居装饰方面可能具有巨大的潜在应用价值。
