Found an interesting story about a company that is testing an electronic bandage.
The bandages consist of polyester material that is interwoven with the company's proprietary 'Prosit' technology. These bandages do something very cool. They conduct a small amount of electricity when wet.
'So what?' you say? Well this helps to kill any germs or bacteria that would otherwise get into a wound and cause it to get infected.
If you want to see some fairly nasty before and after pictures, check out their brochure in pdf format.
