Tiny Turbines Powered by Blood

Sep-13-17 Nanogenerators powered by blood flow could offer an innovative new way to power medical implants.

Developed by a team at Fudan University, the nanogenerators are an improvement over previous versions, which could cause fatal blood clots. The new tiny turbines are made up of a polymeric core wrapped with an ordered array of carbon nanotubes. Termed a fiber-shaped fluidic nanogenerators (FFNG), the device is able to generate electricity from the movement of the solution surrounding it.

According to the team, the FFNG is able to generate more power than similar miniature devices, with a conversion efficiency of more than 20 percent.
