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, which help the heart beat more regularly, offer a lifeline for many patients with cardiac problems but the need for battery power is a limiting factor, since replacing them requires a surgical intervention.
Adrian Zurbuchen of the University of Bern's cardiovascular engineering group aims to get around the problem with his device, using automatic clockwork first developed for pocket watches by Swiss watchmaker Abraham-Louis Perrelet in 1777.
