A team of University of Wisconsin-Madison researchers has developed an implantable, battery-free pacemaker that’s charged by a patient’s heartbeat.
The device has the potential to last an entire lifetime, reducing the risks and costs associated with replacing the devices when their batteries fail.
Led by Pengfei Chen, a postdoctoral scholar in the UW-Madison Department of Materials Science and Engineering, the research appears in the August 19, 2026, issue of the journal Science Advances.
“For a device like this, it’s not just about producing energy. Power density is the most important part. You need to get enough power in a small enough volume,” says Xudong Wang, a professor of materials science and engineering who oversees Chen’s research. “With our technology, we achieved a power output density an order of magnitude higher than previous nanogenerators.”
