Thermoelectric fabrics are a groundbreaking innovation in textile technology that leverage the principles of thermoelectric conversion to transform body heat into usable electricity. They function on the principle of the Seebeck effect, which explains how a temperature differential can produce an electric voltage. This thermoelectric effect forms the basis of these fabrics’ operation, as they harvest and convert the heat emitted by the human body into electrical energy.

Various studies and research, like the one published on Wiley Online Library, have made significant contributions to the development of these fabrics. The findings have not only defined the potential of smart textiles in energy production but also provided key insights into improving their efficiency and durability.
