Researchers led by Queensland University of Technology (QUT) have created an ultra-thin, flexible film that harnesses body heat to generate electricity, potentially replacing batteries for many devices.<\/p>\n\n\n\n<p>This innovative technology, <a href=\"https:\/\/www.science.org\/doi\/10.1126\/science.ads5868\" target=\"_blank\" rel=\"noopener\" title=\"\">published<\/a> in the journal Science, enables the film to be used not only in wearables but also in cooling electronic chips in smartphones and computers. <\/p>\n\n\n\n<p>Zhi-Gang Chen, a professor in the School of Chemistry and Physics at QUT who led the research, emphasized the significance of this development.<\/p>\n\n\n\n<p>&#8220;Flexible thermoelectric devices can be worn comfortably on the skin where they effectively turn the temperature difference between the human body and surrounding air into electricity,&#8221; Chen said in a <a href=\"https:\/\/www.qut.edu.au\/news?id=198149\" target=\"_blank\" rel=\"noopener\" title=\"\">news release<\/a>. &#8220;They could also be applied in a tight space, such as inside a computer or mobile phone, to help cool chips and improve performance.&#8221;<\/p>\n\n\n\n<p>The team, composed of experts from various disciplines, including chemistry, physics and materials science, tackled the longstanding issues of flexibility and efficiency in thermoelectric devices. <\/p>\n\n\n\n<p>Prior research largely focused on bismuth telluride-based thermoelectrics, known for their high efficiency in converting heat into electricity, making them suitable for low-power applications such as health monitors.<\/p>\n\n\n\n<p>In their groundbreaking study, the team introduced a new, cost-effective method to create flexible thermoelectric films using tiny crystals known as &#8220;nanobinders.&#8221; These nanobinders form a consistent layer of bismuth telluride sheets, significantly enhancing both the efficiency and flexibility of the film.<\/p>\n\n\n\n<p>&#8220;We created a printable A4-sized film with record-high thermoelectric performance, exceptional flexibility, scalability and low cost, making it one of the best flexible thermoelectrics available,&#8221; added Chen.<\/p>\n\n\n\n<p>The manufacturing process combined &#8220;solvothermal synthesis,&#8221; which produces nanocrystals in a solvent under high temperature and pressure, with &#8220;screen-printing&#8221; and &#8220;sintering&#8221; techniques. The screen-printing technique facilitates large-scale film production, while sintering \u2014 heating the films to near-melting point \u2014 bonds the particles together, creating a resilient and efficient material.<\/p>\n\n\n\n<p>First author Wenyi Chen, a QUT researcher, stressed in the news release that the team&#8217;s technique &#8220;could also work with other systems, such as silver selenide-based thermoelectrics, which were potentially cheaper and more sustainable than traditional materials.&#8221;<\/p>\n\n\n\n<p>&#8220;This flexibility in materials shows the wide-ranging possibilities our approach offers for advancing flexible thermoelectric technology,\u201d he added.<\/p>\n\n\n\n<p>Beyond powering wearables, this innovation could lead to advancements in personal thermal management. For instance, body heat could drive a wearable heating, ventilation, and air conditioning system, making such devices even more efficient and integrated into everyday life.<\/p>\n\n\n\n<p>While this breakthrough addresses many existing challenges like high costs and complex manufacturing, it also sets the stage for a new era in energy sustainability and electronic device efficiency.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new breakthrough may soon change the way we power our wearable devices.
