Self-Sustaining Leadless Intracardiac Pacemaker Powered by Triboelectric Nanogenerator

New battery-free pacemaker harvests power from every heartbeat

A team of University of Wisconsin–Madison researchers has developed an implantable, battery-free pacemaker that's charged by a patient's heartbeat.

Heartbeats power a battery-free pacemaker designed to last a lifetime

Madison researchers have 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 devices when their batteries fail.

Self-sustaining leadless intracardiac pacemaker powered by triboelectric nanogenerator

Abstract Leadless intracardiac pacemakers (LIP) are a technological breakthrough that offer tremendous benefits to patients, including minimally invasive delivery, improved quality of life, and reduced financial burden. However, limited by its size and capacity, the battery component becomes a major roadblock to further advancing LIP technology toward lifelong, maintenance-free implants without the need for device retrieval or replacement. Here,…

Engineers pioneer a pacemaker that can power itself

A triboelectric nanogenerator harvests energy from each heartbeat to power a battery-free pacemaker, pointing toward implants that could last a lifetime.

Engineers Develop Self-Powered Pacemaker 恒一

A battery-free pacemaker powered by the motion of a beating heart could one day eliminate the repeated replacement surgeries faced by many patients with implanted cardiac devices. Researchers at the University of Wisconsin–Madison have developed an oscillating triboelectric nanogenerator designed to generate electricity inside a leadless intracardiac pacemaker, potentially allowing the device to operate for […]
