Lawrence LeBlond for redOrbit.com - Your Universe Online The artificial pacemaker, a device that helps regulate the human heart through electrical impulses, has been widely used in cardiac patients for decades. However, these patients must undergo regular procedures to replace batteries when they wear out, raising the risk for infections and other complications. But now, researchers believe they have a new form of energy that can power pacemakers well beyond the life of conventional...
A new power scheme for cardiac pacemakers turns to an unlikely source: vibrations from heartbeats themselves. Engineering researchers at the University of Michigan designed a device that harvests energy from the reverberation of heartbeats through the chest and converts it to electricity to run a pacemaker or an implanted defibrillator. These mini-medical machines send electrical signals to the heart to keep it beating in a healthy rhythm. By taking the place of the batteries that power...
