Abstract

In electrowetting-on-dielectric (EWOD) platform, the transfer of droplets from the EWOD boundary region (top plate and bottom plate) to the open region is challenging. The challenge is due to the resistance-like surface tension, friction from the top-plate edge, and the so-called boundary. For this purpose, we designed the top plate to minimize the friction resistance at the boundary. The experiment focused on Gibb's formula and successfully transferred the liquid droplet between the top plate and bottom plate boundary region under a high voltage environment. The threshold voltage for the successful transportation of the droplet between the boundary is 250 V which provides strong pressure to drive the droplet.

摘要

在介电电泳（EWOD）平台中，液滴从EWOD边界区域（顶板和底板）转移到开放区域具有挑战性。这一挑战源于类似阻力的表面张力、顶板边缘的摩擦力以及所谓的边界。为此，我们设计了顶板以尽量减少边界处的摩擦阻力。该实验聚焦于吉布斯公式，并在高压环境下成功地在顶板和底板边界区域之间转移了液滴。液滴在边界之间成功传输的阈值电压为250V，这为驱动液滴提供了强大的压力。
