Researchers from Queensland University of Technology (QUT) have developed an innovative, ultra-thin and flexible film capable of converting body heat into power for wearable devices and potentially cooling electronic chips. Led by Professor Zhi-Gang Chen, the groundbreaking research published in Science addresses critical challenges in creating flexible thermoelectric devices by using a novel approach involving tiny crystals called nanobinders to form consistent layers of bismuth telluride sheets.
The team’s advanced technique employs solvothermal synthesis and screen-printing methods to produce a highly efficient, A4-sized film with exceptional flexibility and low production costs. This technology offers promising applications ranging from powering personal electronics to improving thermal management in devices like smartphones and computers. By demonstrating the potential to transform temperature differences between the human body and surrounding air into electricity, the research represents a significant step toward sustainable and adaptable energy solutions for next-generation electronic devices.
