研究目的
To study the Electrowetting on Dielectric (EWOD) phenomenon theoretically and numerically, focusing on the manipulation of droplets in digital microfluidic systems.
研究成果
The research successfully simulates the EWOD mechanism, revealing a threshold voltage of 50 V for droplet movement and a maximum velocity at 250 V, beyond which no significant increase in velocity is observed. The study contributes to the understanding of EWOD for droplet manipulation in microfluidic systems.
研究不足
The study acknowledges challenges such as the high input voltage required, which can lead to heat generation, increased risk, droplet evaporation, and power supply constraints. Additionally, the Lippmann-Young equation's assumptions may not hold in reality due to factors like surface roughness and droplet conductivity.
