The prototype, detailed in a recent paper published in the journal Advanced Materials, is flexible and durable. Unlike traditional rigid thermoelectric devices, this wearable material retains its functionality even after being punctured and stretched up to 2,000 times. It features a three-layer design with thermoelectric semiconductors in the core surrounded by 3D-printed composites that enhance energy conversion.
This device not only demonstrates the potential to power LEDs directly from body heat, but also has broader applications. It could be integrated into electronics that generate waste heat, such as in data centers, to power sensors and reduce overall power consumption.
The technology could also find applications in virtual reality systems and other wearable devices.
