Plastic Films Turn into Tiny Power Plants: Chinese Researchers Set New Record in Flexible Thermoelectrics

Chinese researchers at the Institute of Chemistry, CAS, have developed a flexible polymer thermoelectric film with a reported zT of 1.64, using a polymer phase‑separation process compatible with spray‑coating. The advance could make lightweight, conformable heat‑to‑electricity devices feasible, though real‑world power output, durability and integration remain to be proven.
