In a groundbreaking advancement, researchers from the Queensland University of Technology (QUT) have engineered a novel semiconductor alloy capable of transforming body heat into electrical energy, potentially revolutionising the power source for wearable devices.

Harnessing Body Heat: The Science Behind the Innovation

The QUT research team, led by Nanhai Li and Professor Zhi-Gang Chen, focused on enhancing a thermoelectric alloy composed of silver, copper, tellurium, selenium, and sulfur. Through a technique known as "vacancy engineering," they manipulated the atomic vacancies within the alloy's crystal structure. This adjustment significantly improved the material's ability to convert thermal energy into electricity while increasing its mechanical flexibility—a crucial attribute for wearable technology.

"The human body consistently emits heat, creating a temperature differential with the surrounding environment," explained Li. "This difference can be harnessed to generate electricity, especially during physical activities when the temperature gap widens."
