Cellulose clothing can generate electricity

Researchers at Chalmers University of Technology have created the first prototype of a conductive tissue capable of charging various gadgets from the heat of the human body. For this, they made special yarns from cellulose.
Every year people surround themselves with an increasing number of various gadgets. So far, no revolution in batteries is expected, which means that all devices require constant recharging. The idea of ​​scientists is to create an effective technology for converting the heat of the human body into electricity.


Previously, a team of researchers from Chalmers University of Technology made significant progress in developing a conductive thread made from silk. This time, the researchers were able to demonstrate an even more impressive result based on wood-based cellulose filaments. During the experiment, the thread was dyed with an electrically conductive biocompatible polymer PEDOT: PSS, which expanded its characteristics by adding new properties. The resulting thread can be sewn into fabric using a household sewing machine, thus obtaining a thermoelectric fabric capable of generating electricity when exposed to heat from one side, for example from the body.

Already now there is an opportunity to establish the production of conductive fabric, and its efficiency is sufficient for charging small gadgets. For example, with its help in the cold, a person generates about 0.2 microwatts of electricity. Scientists emphasize that cellulose has a huge advantage over other materials, since it is non-toxic and does not harm the environment. It is easy to recycle and is capable of withstanding multiple washes. Unfortunately, no information has yet been received on the appearance of the first clothing with conductive threads based on the new technology.
