Researchers at Ulsan National Institute of Science and Technology (UNIST), the Korea Institute of Science and Technology (KIST), and the Korea Electrotechnology Research Institute have developed a thermoelectric paint that can generate electricity from waste heat. The paint could help power homes, vehicles and even ships. In their study, the team presented a new type of high-performance thermoelectric (TE) materials that possess liquid-like properties. These newly developed materials are both shape-engineerable and geometrically compatible in that they can be directly brush-painted on almost any surface. Scientists hope that their finding will pave the way to designing materials and devices that can be easily transferred to other applications.
