'Melt in the body' electronics devised

Ultra-thin electronics
that dissolve inside the body have been devised by scientists in the US
and could be used for a range of medical roles.
The devices can "melt away" once their job is done, according to research published in the journal Science.

The technology has already been used to heat a wound to keep it free from infection by bacteria.

The components are made of silicon and magnesium oxide, and placed in a protective layer of silk.

It is part of a field termed "transient electronics" and comes from researchers who have already developed "electronic tattoos" - sensors that bend and stretch with the skin.

They described their vanishing devices as the "polar
opposite" of traditional electronics, which are built to be stable and
to last...................
