摘要
In this work,we use commercial powder particulates(a cosmetic fixing powder)as triboelectric materials for constructing a triboelectric nanogenerator(CFP-TENG).Through finger pressing,the CFP-TENG generated approximate open-circuit voltage,short-circuit current,and maximum power density values of 1141 V,521μA,and 570.96μW/cm^(2),respectively.Thirty-seven commercial blue LEDs can be easily lit up by the CFP-TENG.Moreover,this TENG,which was designed as a novel palette structure for harvesting mechanical energy from bicycle motion,serves as a self-powered bicycle speed sensor.In addition,the cosmetic fixing powder can be used as an effective material to enhance the triboelectric property of skin.This study provides an effective method for developing a cost-effective TENG without the use of complex surface micro-/nano-texturing.
