A team of medical researchers in the US and Portugal say they've created an electronic device that is applied to skin or organs similar to a temporary tattoo. They hope it may be used to operate prosthetic limbs and treat conditions including Parkinson's disease. 

The team says it could have uses in everything from treating diseases to monitoring health, operating prosthetic, or stimulating flesh and blood body parts.

It was created as a joint effort between Portugal's University of Coimbra and Carnegie Mellon in Pittsburgh.

It's applied to the skin - similar to a temporary tattoo and is controlled through a bluetooth connection.

The key component? This silver alloy that is printed very similarly to how a regular inkjet printer works. That, they say, makes it cheaper and easier to produce than similar projects.
