Thanks to the advances in modern technology, our clothes are gradually becoming more and more functional. Confirmation of this is the latest development of scientists from Chalmers Technical University (Sweden), who managed to create a conductive cellulose thread.
As conceived by the developers, it can be used in textiles capable of generating electricity – in particular, to power miniature wearable gadgets.
The novelty is wood cellulose filaments dyed with the conductive biocompatible polymer PEDOTT: PSS. Their high conductivity can be increased by the addition of silver nanowires. The unique thread can be sewn into fabric using a conventional sewing machine, resulting in thermoelectric textiles that generate electricity when exposed to heat.
According to the doctoral student of the Department of Chemistry and Chemical Engineering of STN Sozan Darabi, such threads will make it possible to create clothes from environmentally friendly materials with built-in electronic and intellectual functions – for example, for monitoring various health indicators.
