A team of engineers at Stanford has demonstrated the feasibility of a super-small, implantable cardiac device that gets its power not from batteries but from radio waves transmitted from a small power device on the surface of the body.
The implanted device is contained in a cube just 0.8 millimeter on a side. It could fit on the head of pin.
The engineers say the research is a major step toward a day when all implants are driven wirelessly. Beyond the heart, they believe such devices might include swallowable endoscopes, permanent pacemakers, and precision brain stimulators.
