Chinese scientists have developed an elastic band that can convert body heat into electrical energy, leading the way for a new future in smart wearables.

Foreign media: Chinese scientists have created the world's first rubber band that can convert body heat into electrical energy, paving the way for self-charging smartwatches and other wearable devices.

The material combines elasticity with efficient thermoelectric conversion performance. Previously, high-performance thermoelectric materials could only achieve flexibility, not elasticity.

This research is based on the thermoelectric principle, using the difference between body temperature and ambient temperature (body temperature is about 37 degrees Celsius, ambient temperature is 20 to 30 degrees Celsius) to generate electricity, which has the potential to provide continuous and stable power for wearable devices, freeing them from the hassle of frequent charging.
