Heart-Powered Pacemaker Frees Patients from Battery Replacements

Researchers at Hanyang University in Seoul have created a pacemaker that harnesses the heart's own movements to generate power, using piezoelectric materials to convert mechanical force into electrical energy. This innovation could lead to devices that last a lifetime without battery replacements.
Traditional pacemakers require battery changes every 5-12 years, posing risks like infections. The new self-powered device aims to eliminate these surgeries, offering a safer, more sustainable solution for patients.
Between 2008 and 2018, over 80,000 deaths and 1.7 million injuries were linked to medical implant failures, highlighting the need for more reliable devices.
