A pacemaker is a small, battery-powered device that controls the heartbeat. Our heartbeats are controlled by a highly efficient, biological electrical system that ensures our heart steadily pumps ...

Mechanical and electrical energy are linked and can be exchanged back and forth. Just like ultrasound converts electrical voltage into pressure or sound, we can engineer similar materials onto ...

Scientists at the University of Chicago have developed a new pacemaker that’s thinner than a human hair, wireless and operated entirely by light from an optic fiber. The non-invasive device could help ...

During an average lifetime, the heart beats more than 2 billion times. To you, it might just be a steady “lub-dub” that speeds up under pressure and slows as you drift to sleep. But behind that rhythm ...

“Wires literally protrude from the body, attached to a pacemaker outside the body,” according to Northwestern University professor of cardiology and biomedical engineering Igor Efimov. This brutal ...

Medtronic engineers knew seven years ago that they wanted to build a pacemaker an order of magnitude smaller than what was out there. But how to do it was a different story. "When we first started, we ...

UW researchers created a sleeve for a pacemaker using piezoelectric materials, which generate electricity when mechanical pressure is applied. Credit: iMatter Lab & Bioengineering ...

Procedure-related infection rates were similar with reconditioned and new pacemakers, according to late-breaking research presented in a Hot Line session today at ESC Congress 2025. Explaining the ...

CHICAGO — One person’s used pacemaker is another person’s treasure. A program to refurbish used pacemakers could expand access to the lifesaving devices. In a clinical trial of nearly 300 people, ...

Several brands of Boston Scientific pacemakers are under recall due to a risk that the devices can permanently enter Safety Mode, according to an alert issued by the US Food and Drug Administration.
