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 ...

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 ...
