Carbon nanotubes used to make batteries from fabrics
Wayne Brooker at Thursday 21st January filed under Competitions
"Ordinary cotton and polyester fabrics have been turned into batteries that retain their flexibility.
The demonstration is a boost to the nascent field of "wearable electronics" in which devices are integrated into clothing and textiles.
The approach is based on dipping fabrics in an "ink" of tiny tubes of carbon, and was first demonstrated last year on plain copier paper.
The new application to fabrics is reported in the journal Nano Letters."
