Graphene-based moving bubble power generation device and manufacturing method thereof

The invention relates to a graphene-based moving bubble power generation device and a manufacturing method thereof. When a bubble moves along a surface of the graphene, ions around the bubble form a dual electric layer on the surface of the grapheme, and a charging and discharging effect is performed between the front end and the tail end of the moving bubble. A voltage is generated between the two ends of the grapheme, the voltage is linear with the volume of the moving bubble, and the polarity depends on the direction of the moving bubble. The invention realizes energy collection by allowingthe moving bubbles to generate the voltage between the both ends of the graphene, and can also be used for detecting the moving speed, direction and volume of the bubble; and the overall device is simple in structure, is economical, has high environmental adaptability, and can be used as a self-powered device of a sea wireless sensor network. 本发明涉及种基于石墨烯的运动气泡发电装置及制造方法，当气泡沿石墨烯表面运动时，由于气泡周围的离子在石墨烯表面形成双电层，并在运动气泡的前端和末端进行充放电作用
