Miniscule turbines generate energy from blood flow to power pacemakers

We’ve known turbines to be hooked up to free-flowing streams of water, supplying energy to electricity grids. We’ve never had turbines being hooked up to arteries to generate energy from the flow of blood before though. Engineers at Switzerland’s University of Bern are busy hammering into place tiny and miniscule turbines capable of being fitted in human arteries that will produce 800 microwatts of electricity, more than enough to power up an average pacemaker, keeping your heart ticking healthily. The device could also help power up neurostimulators, blood-pressure sensors, and other implanted medical devices, working as a revolutionary means of energy to keep in good health.

A medical and technological breakthrough, this little turbine doing the rounds in our arteries could just be the best sustainable means keeping our weak hearts beating in the future.
