Electrowetting Fundamental Principles And Practical Applications -

Ask me anything: Contact angle saturation models, dielectric selection (Cytop vs Teflon AF), or specific EWOD electrode drive schemes.

Electrowetting: Defying Surface Tension with a Voltage Bias Ask me anything: Contact angle saturation models, dielectric

At its core, electrowetting is the modification of the wetting properties of a liquid droplet on a solid surface using an applied electric field. Forget mechanical pumps; we are controlling surface chemistry with electrons. dielectric selection (Cytop vs Teflon AF)

$$cos(\theta(V)) = cos(\theta_0) + \frac{\epsilon_0 \epsilon_r}{2 d \gamma_{LG}} V^2$$ Ask me anything: Contact angle saturation models, dielectric
