Researchers from the Queensland University of Technology (QUT) have developed an ultra-thin, flexible film that could generate electricity from body heat. The film could power next-generation wearable technology, eliminating the need for batteries.
Lasting energy Source
Additionally, the technology could cool electronic chips, making computers or smartphones run more efficiently. Professor Zhi-Gang Chen and his team published their findings in the journal Science. The researchers said they tackled a major challenge in creating flexible thermoelectric devices that converted body heat into power.
Their approach offers a potential sustainable energy source for wearable technology and a cooling method for chips.
“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,” Professor Chen said. “they could also be applied in a tight space, such as inside a computer or mobile phone, to help cool chips and improve performance.”
Chen says there are many potential applications, including personal thermal management, where body heat powers an HVAC system.“However,” he said, “challenges like limited flexibility, complex manufacturing, high costs, and insufficient performance have hindered these devices from reaching commercial scale.”

revolutionary Flexible Thermoelectric Film: A Breakthrough in Wearable Tech
A team of researchers has achieved a notable breakthrough in flexible thermoelectric technology, developing a cost-effective method for producing high-performance films with potential applications in a wide range of wearable devices. This innovation promises to revolutionize the field, offering a more efficient and sustainable approach to energy harvesting.
The research, focusing on Telluride-based thermoelectrics known for their exceptional ability to convert heat into electricity, has yielded a printable A4-sized film boasting record-high thermoelectric performance. This remarkable achievement opens doors for low-power applications such as heart rate monitors, temperature sensors, and movement trackers.
the key to this advancement lies in the use of “nanobinders,” tiny crystals that create a consistent layer of bismuth telluride sheets. This novel technique substantially enhances both the efficiency and flexibility of the resulting thermoelectric film. Professor Chen, a lead researcher on the project, highlighted the meaning of their findings: “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.”
wenyi Chen,the study’s first author,further emphasized the versatility of their approach. he stated, “This flexibility in materials shows the wide-ranging possibilities our approach offers for advancing flexible thermoelectric technology.” The implications extend beyond the immediate applications, suggesting potential integration with other cheaper and more sustainable systems.
This breakthrough has the potential to significantly impact the advancement of wearable technology in the U.S. and globally.The ability to efficiently harvest energy from body heat could lead to longer-lasting and more powerful wearable devices, improving healthcare monitoring, fitness tracking, and other applications. The cost-effectiveness of the new method also ensures wider accessibility and adoption of this innovative technology.
The research team’s success underscores the ongoing advancements in nanotechnology and its transformative potential across various industries. The development of this flexible, high-performance thermoelectric film marks a significant step towards a future where energy harvesting is seamlessly integrated into our daily lives, especially within the rapidly expanding field of wearable technology.
Self-Powered Wearables: The Future is Flexible
Queensland University of Technology researchers have unveiled a groundbreaking flexible film capable of harnessing body heat to generate electricity. This development promises to revolutionize wearable technology and perhaps redefine personal thermal management. Today, we’ll discuss the implications of this exciting discovery with Dr. Alice Lin, a leading expert in flexible electronics at the Massachusetts Institute of Technology.
Introducing the breakthrough
