Sewing thermoelectronics into regular textile

The cellulose yarn, which the researchers present in the article, is practical to work with and could be used to make clothing with smart functions. Using a standard household sewing machine, researchers have sewn the electrically conductive cellulose yarn into a fabric and succeeded in producing a thermoelectronic textile, which can produce a small amount of electricity when the textile is heated on one side, for example by a person's body heat – typically 0.2 microwatt at a temperature difference of 37 degrees Celsius.
