A major challenge for pacemaker manufacturers is its battery, which must be safe, reliable and long lasting.

A pacemaker is a small, electronic, computer-like device that is implanted into the chest to control abnormal heartbeat.

"Unfortunately, when the battery starts to run out, you have to physically remove these devices which requires surgery and re-operation", said Marvin Slepian, the director of interventional cardiology for the University of Arizona Sarver Heart Center.

Slepian has turned to something called piso electronics to figure out how to get away from batteries in implanted devices, such as pacemakers.

Slepian said when piso electronic materials are stricken, they convert the mechanical force of the strike into an electrical current. That makes it possible to convert the beating of the heart, or perhaps the expansion of the lungs, into electricity that can power an implant.

Using piso electronics could mean a shift in medicine, in which people wear devices that are powered by their own bodies. These devices could be implanted internally, or worn in clothing, shoes, and bands, Slepian explained.

He called his vision of the future, the body electric.
