Show Abstract
In this paper, vibration based on liquid surface tension is reported. A prototype vibrator composed of a water film sandwiched between two plates is fabricated and tested. The free and the continuous vibrations (electromagnetic drive) of the proposed vibrator are demonstrated. The mechanical model of the vibrator is also presented. Theoretical analysis and experiments prove the surface tension, which has the advantages of the no-mechanical parts, simple-structure, and self-lubrication, is effective for driving. The liquid surface tension vibrator demonstrates the potential applications in resonating sensors, precision actuator, and mechanical switch.

Show Abstract
A flow focusing junction is integrated into a microchannel to break up droplets into a controllable number and size of daughter droplets. High speed images of the breakup at the flow focusing junction show that the breakup depends on the interplay between interfacial tension, shear force on the interface, and the confinement of the microchannel. Phase diagrams of the splitting performance show that the breakup is controllable by varying the flow rate of the continuous phase or by varying the size of the mother droplet.
