Area of Science:

  • Physics
  • Fluid Dynamics
  • Microfluidics

Background:

  • Drops confined between substrates are fundamental to digital microfluidic lab-on-chip devices.
  • AC electrowetting is a key technique for manipulating fluid interfaces in microfluidic systems.

Purpose of the Study:

  • To investigate the excitation of azimuthal oscillations in sandwiched drops using AC electrowetting.
  • To explore the relationship between driving frequency and selected shape modes.
  • To analyze the fluid transport and mixing capabilities induced by these oscillations.

Main Methods:

  • Periodic modulation of the contact line via AC electrowetting to excite azimuthal oscillations.
  • Tuning the frequency of applied voltage to select specific drop shape modes.
  • Qualitative comparison of experimental results with a theoretical model.

Main Results:

  • Parametric excitation observed, with oscillation frequency being half the contact angle modulation frequency.
  • Drop response to sinusoidal driving exhibits non-sinusoidal "stop and go" behavior.
  • Nonperiodic fluid transport within the drop at approximately 1 mm/s.
  • Resonances occurred at lower frequencies than predicted by the theoretical model.

Conclusions:

  • AC electrowetting provides a method for controlled drop oscillation and shape mode selection in digital microfluidics.
  • The induced fluid transport can lead to very fast on-the-spot mixing in sub-millimeter drops.
  • While a theoretical model offers qualitative agreement, quantitative discrepancies in resonance frequencies warrant further investigation.
