In this modern era, scientists are introducing many innovative things. In this regard, scientists from Peking University in China have created a polymer that converts the heat generated by its stretching into electricity. This development could help create smartwatches that can power themselves.

Experts say this innovative material, which looks like a rubber band, effectively converts its elasticity into electricity. This material works on the principle of thermoelectricity, according to which heat is converted into electricity.

According to scientists, until now all high-quality thermoelectric materials have been characterized by flexibility (in which the material bends to a different shape without breaking) rather than elasticity.

Currently, wearable devices such as smartwatches require batteries or regular charging. This new material can provide continuous power to devices without charging.
