A tiny implantable pacemaker as a pinhead is all set to revolutionise medicine world with its big advantage.
Powered by radio waves from outside the body, the device does not need any battery to operate.
The invention by Stanford University engineers could lead to a host of new medical sensors that could run without batteries. The implanted device is adjustable in a cube less than a millimetre in radius.
Millions of pacemakers, cochlear implants and drug pumps are today helping people live almost normal lives across the globe, but these devices still have some engineering issues including requirement of power through batteries. And batteries are bulky, the journal “Applied Physics Letters” reports.?
In a device like pacemaker, the battery alone accounts for half the volume of the device it powers. Secondly, the batteries have limited lives. New surgery is needed when they are finished, according to the “Daily Mail”.
“Wireless power solves both challenges,” said Ada Poon, professor of electrical engineering at Stanford, who heads the research. Earlier last year, Poon made was in limelight when she demonstrated a wirelessly powered, self-propelled device capable of swimming through the bloodstream.
