Recently, it has been reported that the voltage generation is caused by the movement of the electrolyte in contact with graphene or carbon nanotube (CNT) thin film. These reports show that it is possible to harvest electric energy from a small flow in the environment. Previously, we have reported that the output power was enhanced by increasing the sheet resistance of the CNT film on the basis of the equivalent circuit analysis. In this work, we have further increased the output power by using large-area semiconducting CNT thin film by spray coat method.
