Organic Thermoelectric Elastomers for Flexible Energy Electronics

ABSTRACT With the rapid advancement of wearable electronics and bioelectronics, the construction of flexible energy‐supplying systems that simultaneously integrate high‐efficiency energy conversion, excellent body‐conformability, and mechanical durability has emerged as a critical challenge urgently requiring breakthroughs in the thermoelectric field. Recently, Lei et al. have developed a robust thermoelectric elastomer that simultaneously exhibits a high thermoelectric figure of merit (ZT value), excellent tensile resilience, and low modulus. This innovation overcomes the long‐standing challenge of balancing the “mechanical‐electrical‐thermal” performance of thermoelectric materials, thereby opening up new avenues for the continuous self‐powering and solid‐state cooling of wearable devices.
