Self-powered temperature-changing system driven by wind energy.

ABSTRACT: Research on outdoor, mobile, and self-powered temperature-control devices has always been highly regarded. These devices can reduce energy consumption for cooling and heating, and they have broad market prospects. On this basis, a rotary disc-shaped triboelectric nanogenerator (TENG) with a maximum open-circuit voltage of 6913 V, a maximum short-circuit current of 85 μA, and a maximum transferred charge of 1.3 μC was prepared. We synthesized a ferroelectric ceramic composed of 0.15PbTiO₃-0.85PbSc_0.5Ta_0.5O₃ (0.15PT-0.85PST), which exhibited excellent electrothermal effects at room temperature. By quenching, the electrothermal effect ( Δ T_max) and energy harvesting properties of the device were 1.574 K and 0.542 J/cm³, respect
