A defect or disclination line, prepared at a designed place in a nematic liquid crystal, is used as a template for realizing a microwire directly connected to the electrodes with an accuracy of a few microm. The line attracts and traps silica particles, until self-assembling a complete micronecklace. We then fix the colloids in the necklace by means of pyrrole electropolymerization. The process may be extended to connect many microwires simultaneously. This provides a new route for manufacturing automatic 3D connections, which could be important for electronic applications as Moore's law now seems to reach some limit in 2D.
在向列相液晶中设计的位置制备缺陷或位错线，用作模板，以实现与电极直接连接的微丝，精度可达几微米。该线吸引并捕获二氧化硅颗粒，直到自组装成完整的微项链。然后，我们通过吡咯电化学聚合固定项链中的胶体。该过程可以扩展到同时连接许多微丝。这为制造自动 3D 连接提供了一种新途径，这对于电子应用可能很重要，因为摩尔定律在 2D 上似乎已经达到了某些极限。
