Scientists have created a thermoelectric ring that generates electricity from body heat

Researchers have developed a self-healing, flexible device that converts human body heat into electricity.

A team of scientists from the University of Colorado decided to use the thermoelectric effect to create a flexible system in the form of a ring. As a basis, they took a polymer (polyimine) doped with silver nanoparticles, which is able to restore its chemical bonds after breaking. Then thermoelectric generators were fixed on it in the form of thin plates connected by wires made of liquid metal.

The device uses the temperature difference between body heat and ambient air to generate 1 volt of electrical energy for every square centimeter of skin it touches. Several individual segments can be combined into a wristband that can generate around 5V, which is enough to power small wearable electronics such as a watch or fitness tracker.

The components of the system are completely recyclable, as they can be dissolved or separated in a special solution.

We also previously reported on the development of technology that allows robots to “eat” metal for energy.
