New paradigms of water-enabled electrical energy generation

Water flows on the surface of nanomaterials to form an EDL, enabling the production of electrical energy efficiency. In Section 2.2.1, a detailed introduction was given, and in this section, the focus is on introducing the concept of a heterogeneous water flow for the generation of electrical energy.

Electric power generation using paper materials

In this work, paper is used to generate electricity under moisture ingress. As a result, a piece of untreated print paper (1.5 cm 2 in area) can induce a voltage of 0.25 V and a current of 15 nA. The power output can be conveniently tuned by changing the humidity, temperature and number of devices by simple series/parallel connections.
