英文摘要	U.S. Department of Energy, Office of Basic Energy Sciences [DE-FG02-07ER46394]; "thousands talents" program for pioneer researcher and his innovation team, China; NSFC [61174017]; Chinese Scholars Council; New technologies that can scavenge ambient environmental energy have attracted increasing interest in the past decades. Recently, triboelectric nanogenerator (TENG) has been demonstrated as a powerful approach for harvesting various forms of mechanical energies. In this work, a newly designed TENG is demonstrated by coaxially integrating multiple layers disk TENGs into a whole system, which transforms the fluid flow into rotation motion of multiple layers disks and generates a multiplied electrical output. To achieve the effective structural integration and output multiplication, a D-shape shaft is adopted to facilitate the synchronized relative rotation of all the segmentally-structured disk layers and light weight and low stiffness springs are employed to ensure the intimate contact of the tribo-surfaces. With the above design, the nanogenerator delivers an open-circuit voltage up to similar to 470 V and a short-circuit current density of 90.6 mA/m(2), corresponding to an instantaneous maximum power density of 42.6 W/m(2) (2.68 kW/m(3)) at a rotation speed of 1000 rpm. By combining the TENG with a water turbine, the device can be effectively driven by a water flow from a common household faucet. This technology represents an important advance of TENGs toward practical applications and shows great potential in hydroelectric power and wind power industries. (C) 2014 Elsevier Ltd.
