A path to new nanofluidic devices applying spintronics technology

Japanese scientists have elucidated the mechanism of the hydrodynamic power generation using spin currents in micrometer-scale channels, finding that power generation efficiency improves drastically as the size of the flow is made smaller. They experimentally demonstrated the fluid power generation phenomenon in the laminar flow region and confirmed that in the laminar flow region, energy conversion efficiency was increased by approximately 100,000 times.
