Thermo-Electric Material May Power Battery-free Cardiac Pacemaker

Wednesday, November 9th, 2011

Japanese researchers have developed a material that can generate power after implantation by absorbing light from outside the body. The technology is being applied to the development of a battery-free cardiac pacemaker. Currently, the lithium-ion batteries that power pacemakers need to be replaced every five to 10 years, requiring users to ...

New Heart Cell Stimulation Technique Could Result in Light-Controlled Pacemaker

Thursday, August 11th, 2011

A study recently published in Circulation: Arrhythmia & Electrophysiology, a journal of the American Heart Association, details a new technique that could result in a light-controlled pacemaker. The technique uses low-energy light to stimulate heart muscle cells.

Bern Researchers Develop Turbines Designed to Use Hydraulic Power of the Heart to Run Medical Devices

Thursday, May 26th, 2011

Researchers at the University of Bern and the Bern University of Applied Sciences in Switzerland have developed small turbines that can fit into arteries, writes Lucas Laursen in an article for the IEEE Spectrum website. The turbines are designed to power medical devices such as pacemakers by utilising the hydraulic power ...

Scientists Address Hacking Risk for Heart Devices

Thursday, September 4th, 2008

A pacemaker may not seem like an obvious target for a hacker to pursue. But in March of this year, US researchers demonstrated they could hack an implantable cardioverter defibrillator using relatively inexpensive equipment. Although the risk may be remote, the potential implications are troubling, to say the least, because ...
