N2 - Graphene has already been verified to have potential applications in sensor development due to its unique properties, such as large specific surface area, high carrier mobility, conductivity and optical transparency. Here, we discuss our development of a micro bubble generator that could be used to generate and actuate micron-scale bubbles based on monolayer graphene made from chemical vapor deposition (CVD). This micro bubble generator could generate bubbles with diameter of 2 ∼ 65 microns in water. The bubble nucleation power and energy of a graphene heater (7 μm by 30 μm) are 16 mW and 1.6 mJ, respectively. This power is comparable with that of the bubble generator using metal heating elements and carbon nanotubes. Moreover, the resistance-temperature and the current-voltage properties of the fabricated graphene heater are also reported. The experimental results also demonstrated that the monolayer graphene could be used for bubble generation with controllable micro bubble sizes.
