We report a wearable electrofluidic actuation system, which exploits the alternating current electrothermal (ACET) effects to engineer biofluid flow profiles on the body. The wearable ACET flow is induced with the aid of corrosion-resistant electrode configurations (fabricated on a flexible substrate) and custom-developed, wirelessly programmable high frequency (MHz) excitation circuitry. Various tunable flow profiles are demonstrated with the aid of the devised flexible ACET electrode configurations, where the induced profiles are in agreement with the ACET theory and simulation. The demonstrated capabilities rendered by the presented system create new degrees of freedom for implementing advanced bioanalytical operations for future lab-on-the-body platforms.
我们报告了一种可穿戴电液致动系统,该系统利用交流电热(ACET)效应来设计人体上的生物流体流动剖面。可穿戴 ACET 流动是借助耐腐蚀的电极配置(在柔性基板上制造)和定制的、无线可编程的高频(MHz)激励电路来诱导的。借助设计的柔性 ACET 电极配置,演示了各种可调谐的流动剖面,其中诱导的剖面与 ACET 理论和模拟相符。所展示的系统功能为未来的体上实验室平台实现先进的生物分析操作创造了新的自由度。
