“…The improved wetting is a consequence of the lowering of the effective solid-liquid interfacial energy through electrostatic energy stored in the capacitor formed by the droplet-insulatorelectrode system. The dependence of the effective soild-liquid interfacial tension, g SL , on the applied voltage, V, is given by Lippmann's equation: 22 (1)…”

“…Electrostatic modulation of the interfacial tension between a solid electrode and conducting liquid phase is known as electrowetting. [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] Since electrical fields are easily modulated and can be precisely localized through the use of photolithographically defined electrodes, electrowetting can provide a very high level of control across the surface of a substrate. Electrowetting has previously been investigated for micro-actuation in optical applications where the shape of a liquid lens was varied 29,30 or the capillary filling of a matrix of columns or porous material was controlled by an applied voltage.…”

The serviceability of microfluidics-based instrumentation including 'lab-on-a-chip' systems critically depends on control of fluid motion. We are reporting here an alternative approach to microfluidics based upon the micromanipulation of discrete droplets of aqueous electrolyte by electrowetting. Using a simple open structure, consisting of two sets of opposing planar electrodes fabricated on glass substrates, positional and formational control of microdroplets ranging in size from several nanoliters to several microliters has been demonstrated at voltages between 15-100 V. Since there are no permanent channels or structures between the plates, the system is highly flexible and reconfigurable. Droplet transport is rapid and efficient with average velocities exceeding 10 cm s(-1) having been observed. The dependence of the velocity on voltage is roughly independent of the droplet size within certain limits, thus the smallest droplets studied (approximately 3 nl) could be transported over 1000 times their length per second. Formation, mixing, and splitting of microdroplets was also demonstrated using the same microactuator structures. Thus, electrowetting provides a means to achieve high levels of functional integration and flexibility for microfluidic systems.

“…Among numerous proposed mechanisms to provide the required actuation of microdroplets, the mechanisms based on capillary forces are particularly advantageous for small scales, since capillary forces dominate on these dimensions and provide enhanced control and localization. 5,6,[9][10][11][12] The electrowetting phenomenon, in particular, is highly advantageous as it can provide electrostatic changes of the interfacial tension between a solid electrode and a liquid [13][14][15] at a very high speed. 16 Open systems and covered systems are two different types of digital microfluidic systems.…”

In situ characterization of microdroplet interfacial properties in digital microfluidic systems

et al. 2010

Real-time characterization of digital microfluidic lab-on-a-chip devices is important for biological and chemical applications in which the properties of the microdroplet are time variant. In this paper, a method for in situ characterization of microdroplet interfacial properties is introduced. The proposed characterization method relies on two submodules, namely the contact angle and capacitance sampling submodules, in a digital microfluidic system. In the contact angle measurement submodule, the microdroplet profile is acquired and an accurate contact angle is determined. In the capacitance sampling submodule, the capacitance of the system is measured by means of an activation voltage signal. For verification purposes, the results obtained from the proposed method are compared to the Lippmann-Young equation. The results are in excellent agreement with previously reported values. Finally, the proposed submodules are used to characterize the interfacial properties of a microdroplet containing an aqueous solution of bovine serum albumin (BSA) in which adsorption is a predominant effect. The results show the temporal behaviour of both microdroplet interfacial properties and dielectric characteristics.

A lattice Boltzmann model was proposed to simulate electrowetting-on-dielectric (EWOD). The insulative vapor and the electrolyte liquid droplet were simulated by the lattice Boltzmann method respectively, and the linear property between cosine of contact angle and the electric field force confirms the reliability of this model. In the simulation of electrolyte flowing in a rough-wall channel under an external electric field, we found that a narrow channel is more sensitive than a broad channel and the flux decreases monotonously as the electric field increase, but may suddenly increase if the electric field is strong enough.
