A research team from the Institute of Chemistry at the Chinese Academy of Sciences has triumphantly developed a plastic thermoelectric film featuring an irregular multilevel pore structure. This innovation has achieved a thermoelectric figure of merit (zT value) surpassing 1.64, setting a new global benchmark for the performance of flexible thermoelectric materials within the same temperature range. This cutting-edge material has the capability to transform surplus body heat into electrical energy, thereby offering a continuous power supply for wearable gadgets, IoT sensors, and beyond. Looking ahead, it is anticipated that this technology will facilitate the charging of smartwatches, mobile phones, and various other devices solely through the utilization of body temperature. The material's distinctive 'porous-disordered-narrow-channel-ordered' architecture enables the decoupling and synergistic enhancement of both electrical and thermal transport. Moreover, its preparation process is fully compatible with spray coating techniques, which not only substantially cuts down on costs but also propels the practical application of flexible thermoelectric materials forward. This groundbreaking accomplishment was featured in the esteemed international academic journal Science on March 6, 2026.
