Electroosmotic Flow (EOF) enables fluids to be pumped along a surface or in a channel and finds applications in microfluidics and lab-on-a-chip technology. Theoretical results indicate that this flow can be enhanced by more than two orders of magnitude when specific configurations of the electrodes and superhydrophobic surfaces are employed, compared to smooth surfaces. This would enable a whole new spectrum of applications. Using the insights from other subprojects and their wetting characterization, the project intends to experimentally investigate the flow enhancement using these EOF configurations, and then to address the question of optimal design.

电流流（EOF）使流体可以沿表面或通道中泵送，并在微流体和实验室中找到应用。理论结果表明，与光滑的表面相比，当使用电极和超疏水表面的特定构型和超疏水表面时，可以通过两个以上的数量级来增强这种流动。这将实现全新的应用程序。该项目使用其他副标理及其润湿表征的见解，旨在通过这些EOF配置实验研究流量增强，然后解决最佳设计问题。
