Highly conductive and stretchable conductors fabricated from bacterial cellulose

Highly conductive and stretchable conductors from bacterial cellulose (BC) can be fabricated through a simple and inexpensive method using bacterial cellulose pellicles as starting materials, which can be produced in large amounts on an industrial scale via a microbial fermentation process. The prepared pyrolyzed BC/polydimethylsiloxane composites exhibit highly stable electric conductivity even under high stretching and bending strain.
