Scientists have been working for years on finding a way to harvest ambient energy continuously to power biomedical implants. The aim is to keep these vital implants running without the need for batteries, multiple invasive surgeries, and the like. From solar power to friction, to the energy produced when glucose breaks down or body temperature shifts, every rock is being turned over, looked under, and presumably considered for its potential as an energy source, too.
Now, bioengineers at the University of Illinois at Urbana-Champaign say they are closing in on this goal. Perhaps the holy grail of biomedical energy harvesting is using nearby organs; the energy generated by our own hearts and lungs is so, well, reliable.… Read more
