Since the 1950s pacemakers, which use electrical impulses to regulate a beating heart, have shrunk substantially, as have their power packs. But scientists would dearly love to get rid of the batteries altogether. Even the best modern ones run out every 7-10 years and patients must undergo surgery to have replacements installed. The process can be painful, expensive and can lead to infection. One approach, being pursued by some researchers, is to deliver the necessary energy wirelessly. Some designs beam energy to a receiving coil in an implanted device, and others use an external pacemaker that wirelessly stimulates an electrode implanted in the heart. Another possibility is to scavenge energy from the natural processes occurring in the patient's body. In 2011 a group of Swiss engineers installed a tiny turbine inside a simulated artery which was propelled by a bloodlike fluid flowing through it. And now Amin Karami and his colleagues at the University of Michigan have figured out a way to power a pacemaker by harvesting energy produced by the very heart it is nudging along.
