Researchers at the University Hospital of Bern have used ETA watch movements embedded on the hearts of pigs to power a pacemaker, a move that could bring clockwork to our inner organs sooner than later.
The researchers believed that the beating heart could move the oscillating weight if they reduced the radius and added higher mass. To test it they tore down and ETA movement, cut a smaller weight out of platinum, and finally added a tiny autoquartz generator to convert mechanical to electrical engird. When they tested it in pigs they were able to generate 6 microwaves of power – enough to run a pacemaker.

The best thing? The researchers had to depend on Swiss watchmakers to modify the movements.
“We are not able to modify such highly complex clockwork on our own,” said one.
Thank you for reading this WristWatchReview post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
WristWatchReview is one of the few remaining truly independent watch news outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent watch sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis. We don't play the games the other sites play and we've paid for it when it comes to ad revenue.
We would love for you to support us on Patreon and every little bit helps. Thank you.
