Science carries a paper, called Epidermal Electronics, which has such wide implications that Nature carries news of it:

‘Electronic skin’ has been developed that records heartbeats, brain activity and muscle contractions as accurately as bulky conventional electrodes, yet is no thicker than a human hair.

The patch, created by John Rogers, a materials scientist at the University of Illinois, Urbana-Champaign, and his colleagues, consists of a flexible and stretchy lattice of sensor-laden circuits. It can be applied and removed like a temporary tattoo, and sticks to skin without adhesives.

The electronic skin can also do things that conventional medical sensors cannot. When placed on the throat, for example, it senses spoken words well enough to control a simple computer game.

“We focused on the throat because it really highlights the mechanical invisibility of these epidermal electronics, even on a sensitive part of the body,” says Rogers.

Great for instant blogging: just say it and the world knows all about it!
