Background:

Electrowetting on Dielectric (EWOD) systems are advancing with simplified fabrication and low-voltage actuation.
EWOD actuators offer potential applications in Radio Frequency (RF) devices for dynamic reconfiguration of frequency and bandwidth.

Purpose of the Study:

A 3D numerical FEM model was employed to simulate velocity profiles and viscous forces within thin droplets.

Main Results:

The analytical model demonstrated less than 7.8% error in predicting maximum plate velocities compared to experimental data.
The 3D FEM model provided insights into droplet velocity profiles and viscous forces, capturing variations not experimentally measurable.
The proposed EWOD system features a simple 2D manufacturing process, enabling integration with RF circuits and offering a compact, portable, and cost-effective solution.

Conclusions:

The validated analytical and numerical models provide a comprehensive understanding of EWOD actuation dynamics and performance tradeoffs.
The developed EWOD system is reliable, cost-effective, and suitable for harsh environments due to its lack of mechanical components.
This research advances EWOD applications in dynamic RF devices, paving the way for improved real-time frequency and bandwidth adjustments.
