A new clockwork heart pacemaker does away with batteries according to Yahoo News. Swiss engineers, famous for making the world’s finest watches, are turning their hands to cardiology with a prototype battery-less pacemaker based on a self-winding wristwatch. Current pacemakers need for battery power is a limiting factor, since replacing them requires a surgical intervention.
“This is a feasibility study. We have shown that it is possible to pace the heart using the power of its own motion,” Zurbuchen, the head engineer said.
Automatic watches work because they have an eccentric weight that pivots when the wearer’s arm moves. This rotation progressively winds a spring that then turns the watch mechanism. In the new Swiss pacemaker, the mechanical spring unwinds to spin an electrical micro-generator.
The research is still at an early stage and there is, as yet, no schedule for human testing. However, this could prove a major innovation in both healthcare and the watch-making industries.
