A new generation of battery-free surveillance devices which can be implanted under the skin and transmit over huge distances via wireless have been developed by scientists.

Researchers are working on nano machines that could be injected into the arms of patients and then report back to doctors who are monitoring them from miles away.
They would be powered by the motion of a person walking, or even the pulse of a blood vessel, so would never stop working until the person died

The technology could also be used in CCTV cameras attached to small flying craft which use their own motion to power themselves.
Such devices could be used by hospitals to locate patients or perhaps check if they are following their treatment plan.

But they will also be of interest to the military and the criminal justice system which is constantly on the lookout for new ways to spy on criminals.
The advancements were reported in the journal Nano Letters by Zhong Lin Wang of Georgia Tech University in the U.S.
