According to Singapore’s “Lianhe Zaobao†reported on September 1st, Swiss engineers are famous for making the world’s finest watches. Now they turn their attention to cardiology and have created the first watch principle that is automatically wound up. Cardiac pacemaker.
According to reports, current pacemakers on the market can help patients with more regular heartbeats, giving patients with heart disease a chance, but because existing pacemakers must use batteries, this limits the use of pacemakers because The replacement of the battery also requires surgery, and the patient is at risk of infection.

Zebu Chen, a researcher at the Cardiovascular Engineering Group at the University of Bern, Switzerland, used the automatic clockwork structure created by the Swiss watchmaker Bertel in 1777 for pocket watches, hoping to overcome this problem.
Just as a watch can automatically wind up when walking on the wrist, a pacemaker made with a clock principle can use the heart muscle to make a current, which requires the pacemaker to connect directly to the beating heart.
Zebu Chen said that the current experimental system has only been tested on pigs, and the heartbeats of these animals have been successfully adjusted to an average of 130 per minute.
He said: "This is a feasibility study. We have confirmed that pacemakers can use the heart muscles to generate current."
It is understood that the research is still in its infancy, and so far there is no plan to test it in humans.
Zebu Chen revealed that he has not yet sought a business to discuss the partnership, but said that "it is time to find someone to invest."
Prior to this, researchers in the United States had injected a gene into the heart of pigs and successfully developed a "biological pacemaker" that could treat abnormal heart rhythms. According to reports, if it is confirmed that it is also effective in the human body, this "biological pacemaker" may one day replace the electronic pacemaker.
