A flexible electrical circuit one-fifth the thickness of cling film & weighing less than a feather could give doctors the chance to implant sensors inside the body, its Japanese developers say.
The team at the University of Tokyo said the device on an ultra-thin film is unique since it works even after it has been crumpled into a ball or stretched.
Researchers unveiling the circuit said it could be used to monitor all sorts of physical data, such as body temperature and blood pressure as well as electronic pulses from muscles or the heart.
For people who can only move their tongue, the sheet might be placed on the roof of the mouth and serve as a touch pad to operate a communications device, team members said.
"This can be attached to all sorts of surfaces and does not limit the movement of the person wearing it," said professor Takao Someya of his research, which was being published in the journal Nature on Wednesday.
