摘要: Abstract A low-power-consuming, self-powered wearable personal thermal management (PTM) device could minimize our reliability on external power sources. Herein, we describe the fabrication of a PTM providing thermotherapy that can be wirelessly heated, with warmth preservation and heat produced via triboelectric effect. Initially, ferromagnetic porous spongy FexCo1−xP nanostructures were synthesized uniformly over surface woven Kevlar fiber (WKF). Synthesized MXene was then dispersed in polydimethylsiloxane (PDMS) prepared as composite WKF/FexCo1−xP. The combined effect resulted very effective Joule heating (74 °C at 3 V), behavior induced wireless heating. dense interrelated structure created by incorporation helped to maintain body (an enhancement 40.1% compared bare WKF/PDMS) reflecting almost all infrared radiation (97.7%) back body. also exhibited high impact resistance (131.4% for use smart armor. Additionally, maximum density 1.3 mW cm−2 low frequency 5 Hz capable harvesting energy from human motion wind, indicating potential self-heating ability composite.
