Description
Summary: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.
