A team of American biomedical engineers has developed a device similar to a traditional pacemaker, but it generates electricity on its own using the patient’s blood flow, eliminating the need for batteries that typically require replacement every 5–10 years.
The device relies on a flexible nanogenerator coated with piezoelectric material, which bends with each arterial pulse, producing tiny electrical charges with every heartbeat to power the device. This technology allows the device to function for decades without any surgical intervention.
Current devices are limited by battery life, and patients often require repeated surgeries, which carry risks of infection and tissue damage. With this innovation, doctors can significantly reduce these risks and costs, while giving patients peace of mind that their device will not suddenly fail.
Early animal tests showed that the device generates a stable electrical output sufficient to regulate heart rhythm. Researchers are now working on miniaturizing the technology to enable implantation using minimally invasive surgical methods, reducing recovery time.
This system could also be expanded to power biosensors, drug delivery pumps, and neural stimulators, effectively turning the human body into a sustainable energy source for medical devices.
If this innovation reaches the market, it could mark a true turning point in medical devices, transforming implants into permanent, self-sufficient solutions rather than temporary fixes.
