... A QUT-led research team has developed an ultra-thin, flexible film that could power next-generation wearable devices using body heat, eliminating the need for batteries. This technology could also be used to cool electronic chips, helping smartphones and computers run more efficiently.

Professor Zhi-Gang Chen, whose team's new research was published in the journal Science, said the breakthrough tackled a major challenge in creating flexible thermoelectric devices that converted body heat into power. This approach offers the potential of a sustainable energy source for wearable electronics, as well as an efficient cooling method for chips....
