摘要：

We developed a water-elcctrokinetic energy harvester using a flexible woody, carbon film (FWCF). The proposed device induced streaming current/voltage by water-vapor flow and thermal-evaporation flow in natural microchannels of wood. which called tracheid. In addition, high specific area of the FWCF can improve the output. The fabricated device showed a streaming voltage of about 9.7 mu V with the water-vapor flow. Moreover, the output of the device were enhanced by thermal-evaporation flow. The maximum output voltage was 421.3 mu V. After stabilization, 217.8 mu V was continuously observed over 30 minutes at 80 degrees C. These results indicate that the proposed FWCF based water-electrokinetic power generation device has a high potential in power sources for Internet of things society.
