论文摘要
本文中，我们描述了具有浮动顶电极的双板电气电视系统的新型设备配置。由于常规的双板EWOD设备需要在顶板上建立接地电极，因此在封装过程中会导致额外的制造同谋和成本。在这项工作中，我们发现，通过仔细设计电极布置和配置驱动电子电路，可以在顶板上使用浮动电极维持液滴驱动力。这可以提供在顶板上集成其他电化学感测功能的可能性。我们使用有限元分析和制造系统来验证该理论，结果表明，一旦满足设计考虑，浮动的顶部电极EWOD系统非常可靠且可重现。
Herein, we describe a novel device configuration for double-plate electrowetting-on-dielectric system with a floating top-electrode. As conventional double-plate EWOD device requires a grounded electrode on top-plate, it will cause additional fabrication complicity and cost during the encapsulation process. In this work, we found that by carefully designing electrode arrangement and configuring driving electronic circuit, the droplet driving force can be maintained with a floating electrode on the top-plate. This can provide the possibilities to integrate additional electrical or electrochemical sensing functions on the top-plate. We use both finite element analysis and fabricated system to validate the theory, and the results indicate that floating top-electrode EWOD systems are highly reliable and reproducible once the design considerations are fully met.
