Chinese scientists create flexible, efficient plastic material that turns body heat into electricity for wearable tech.
Researchers at the Chinese Academy of Sciences have developed a flexible, plastic-based thermoelectric material that converts body heat into electricity with a record efficiency of 1.64 at 70°C.
The material’s sponge-like porous structure blocks heat while guiding electrons through aligned pathways, generating 9 millivolts from a 10 cm by 8 cm piece on human skin.
Designed for industrial printing, it could enable mass production of wearable devices powered by body heat, potentially supporting medical sensors and green energy systems, though cost and stability improvements are still needed.
