Abstract
The invention provides an application and energy collection and motion sensing method of graphene in motion liquid drop energy conversation. When liquid drops on the surface of the graphene move, due to the charging and discharging effects of double electrode layers formed by ions inside the liquid drops on the surface of the graphene at the front end and the tail end of liquid drop motion, a voltage can be generated at the two ends of the graphene in the liquid drop motion direction. The linear relation is formed between the voltage and the speed of liquid drop motion, and polarities depend on the liquid drop motion direction. Energy collection and sensing of the liquid drop motion speed, direction and time are achieved through the voltage generated at the two ends of the graphene through the moving liquid drops.
