A wearable DC tribovoltaic power textile woven by P/N-type organic semiconductor fibers

Abstract

High performance direct current (DC) textile power supply is an urgent demand for wearable electronics. Herein, we present a wearable DC textile power woven by P/N-type organic semiconductor fibers based on the tribovoltaic effect. The hydrophobic P-type semiconductor PEDOT: PF and N-type semiconductor poly(benzodifurandione) are woven into a spiral fiber (SF). By serial/parallel combination, the SFs are woven into a wearable DC textile power (WDP). The WDPs can provide a DC output of 40 V, 2.2 mA, and its power density can reach 1.05 W/m2, which is approximately 75 times higher than that of previous textile triboelectric nanogenerators. With excellent human morphology adaptability and long-term stability of 72,000 cycles, the WDPs can directly power electronic devices such as commercial lithium-ion batteries, mobile phone and ink electronic screens. The high-performance WDP provides a promising strategy for the practical application of tribovoltaic effect in the field of textile power supplies and smart wearable electronics.
