This research presents a self-powered temperature control system using a rotary disc-shaped triboelectric nanogenerator (TENG) and ferroelectric ceramic (0.15PT-0.85PST). The TENG harvests wind energy, generating a high-voltage electric field to drive the electrothermal effect in the ceramic, enabling temperature changes. The system achieved a temperature change of 0.49 K in 276s, representing a 31% reduction in cooling/heating time and an 81% increase in temperature change compared to previous methods. Optimized versions further increased heating and cooling to 1.19 K and 0.93 K, respectively, showcasing the system's potential for commercial applications, particularly in reducing energy consumption for cooling and heating in alignment with carbon emission reduction goals.
