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 power textile 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 power textile (WDP). The WDPs can provide a DC output of 40 V, 2.2 mA, and power density can reach 1.05 W m⁻², approximately 75 times higher than that of previous textile triboelectric nanogenerators. With excellent human morphology adaptability and long-term stability of 72 000 cycles, electronic devices such as commercial lithium-ion batteries, mobile phones and ink electronic screens can be directly powered by the WDPs. The high-performance WDP provides a promising strategy for the practical application of the tribovoltaic effect in the field of textile power supplies and smart wearable electronics.
