Scientists Unveil Thermoelectric Rubber Band That Converts Body Heat into Electricity
In a groundbreaking development, scientists at Peking University have created the world's first rubber band capable of converting body heat into electricity. This innovation could revolutionize wearable technology by eliminating the need for bulky batteries or frequent charging.
The new material operates on the principle of thermoelectricity, where temperature differences generate electrical current. By harnessing the natural temperature gradient between the human body (approximately 37°C) and the surrounding environment (typically 20–30°C), the rubber band generates electricity continuously.
Notably, this thermoelectric elastomer maintains its elasticity even when stretched up to 150% of its original length and can withstand strains exceeding 850%. This combination of flexibility and high energy conversion efficiency paves the way for next-generation self-powered wearables.
Potential applications include self-charging smartwatches, health monitoring patches, and other wearable devices that can generate their own power from body heat.
