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 ...

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 ...

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

Accurately measuring electrical signals and calcium levels in the heart can lead to earlier treatment of potentially fatal conditions, such as heart attack or congestive heart failure. Calcium plays ...

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, ...
