Fabric batteries make their debut in wearable electronics

08
Apr '10
Researchers from the University of Stanford have used the carbon nanotube ink which turns ordinary fabrics into wearable batteries. Innovations in wearable electronics have made fabrics that can act as batteries.

A special ink made of carbon nanotubes are used to change ordinary cotton or polyester fabric into batteries. These start functioning when they are folded and twisted.

The ink is made from single walled carbon nanotubes. When the fabric is dipped in the ink, carbon nanotubes get aligned on the existing fibres in the fabric. When the fabric dries, it still retains its flexibility and stretchability while becomes conductive.

Researches also proved that loading the fabric with psuedocapacitor materials increased the areal capacitance of the fabric 24 times more.

The process is very simple and scalable as dyeing fibres and fabrics. The interwoven fibres of fabrics are similar to those of paper and are suited to absorb the nanotube ink thereby maintaining an electrical connection across the whole area of the apparel.
