Tiny turbine in human artery harvests energy from blood flow

(PhysOrg.com) -- A small turbine located inside a millimeters-wide human artery could harvest enough energy from blood flow to power implanted medical devices, such as pacemakers and drug-delivery pumps. The concept has been presented by researchers at the University of Bern and the Bern University of Applied Sciences during the Microtechnologies in Medicine and Biology conference in Lucerne, Switzerland, earlier this month.
