导电表面和图案处于电子研究的最前沿，需要变得更小并创建更复杂的电子设计和设备，同时仍然保持易于制造。本文研究了一种用于微尺寸电驱动器件的图案化导电迹线的方法，重点是实现和图案化复杂的几何形状。该方法包括设计和制造亲水性微结构沿着通道与疏水边界上的设备的表面。通道连接到设备外部的较大电极。当将导电溶液施加到外部电极区域时，亲水性形态刺激溶液沿通道沿着供给并填充预先设计的图案。因此，本研究的主要目的是探索不同的微结构设计，以增加不同取向表面的液体电极图案化的表面亲水性。由于涉及到许多物理力、材料域和相互作用，因此选择实验方法来研究通过润湿进行表面电极微图案化的方法。微结构化的表面是使用双光子聚合3D打印技术，由于其上级分辨率。完成了对各种形貌的分析，制作了具有选定亲水形貌的微尺寸机电器件，用液体电极进行图案化，并进行了测试。本文的研究结果进一步发展的电极图案化，并帮助确定哪些亲水性微结构显示上级图案化能力沿着水平和垂直矢量。
Conductive surfaces and patterns are at the forefront of electronics research with a need to go smaller and create more intricate electronic designs and devices while still maintaining easy manufacturability. This paper investigates an approach of patterning conductive traces for microsize electrically driven devices with the focus on enabling and patterning complicated geometries. The approach includes the design and fabrication of hydrophilic microstructures along the channels with hydrophobic borders on devices’ surfaces. The channels are connected to larger electrodes outside the device. When a conductive solution is applied to the outside electrode area, hydrophilic morphologies stimulate the solution to feed along the channels and fill the predesigned patterns. Therefore, the major objective of this study is to explore different designs of microstructures to increase surface hydrophilicity for liquid electrode patterning for variously oriented surfaces. Due to numerous physical forces, material domains, and interactions involved, experimental approach is selected to study the method of surface electrode micropatterning through wetting. Microstructured surfaces are fabricated using the two-photon polymerization 3D printing technique due to its superior resolution. Analysis of various morphologies is completed, a microsize electromechanical device with selected hydrophilic morphologies is fabricated, patterned with liquid electrode, and tested. The findings in this paper further the development of electrode patterning and help determine which hydrophilic microstructures show superior patterning ability along horizontal and vertical vectors.
