One of the problems with wearable medical devices is the electronics for sensing physiological parameters , process the data and communicate with a host computer.

Cotton is easy to wear but it is, well, cotton. What if one weaves electronics into this unlikely platform. That is just what researchers from USA, France and Italy have done.

They made conformal coatings of nano particles of Gold on cotton fibres and used them to make electrochemical transistors.

We may soon see wearable devices to monitor vital functions that may be paraded on ramps.
