Humidity micro power generation device based on dust-free paper and ink and preparation method and application thereof

The invention provides a humidity micro power generation device based on dust-free paper and ink and a preparation method and application thereof. The dust-free paper soaked in the ink and dried is placed in the air; moisture is absorbed from the environment by coating the dust-free paper with the LiCl solution, the moisture interacts with oxygen-containing functional groups in the ink to generatehydrated hydrogen ions, and the hydrated hydrogen ions are transmitted from one end to the other end along microporous channels in the paper to generate voltage and current, so that power is suppliedto electronic devices. The paper-based micro power generation device prepared can generate 0.35 V voltage under the environmental conditions of 50% relative humidity and 20 DEG C, can stably output the voltage for more than 100 hours, and has a remarkable effect.
