How long before an alternative is found to battery-powered pace makers like this? (Photo: khuruzero/Shutterstock)
Research using a prototype piezoelectric energy-harvesting device developed by the University of Michigan suggests that the human heart provides more than enough energy to power a pacemaker, according to a statement released by the American Heart Association. The research has led to fresh speculation that piezoelectricity, electricity converted from mechanical stresses undergone by a generator, may one day provide an alternative to battery-powered pacemakers that need to be surgically replaced as often as every five years.
