The implantable pacemaker, a medical marvel that has extended millions of lives since its invention nearly 60 years ago, is getting a 21st century makeover.

First came a wireless version; these pacemakers, which are the size of a AAA battery and placed inside the heart via a catheter through the leg, are being tested in humans in the United States, Canada and Australia.

Now, researchers are developing technology to make these devices battery-free. The advancement is based upon a piezoelectric system that converts vibrational energy – created inside the chest by each heartbeat – into electricity to power the pacemaker.
