本文介绍了几种低成本在纸上制作柔性电子线路的方法。所述电路包括i）金属线（例如，锡或锌），其通过蒸发、溅射或喷涂沉积在衬底上，和ii）分立的可表面安装的电子元件，其用导电粘合剂直接紧固到导线上。这些电子电路-像传统的印刷电路板-可以与连接在基板两侧的电子元件一起生产。然而，与由玻璃纤维、陶瓷或聚酰亚胺制成的印刷电路板不同，纸可以被折叠和折痕（重复地）、成形以形成三维结构、使用剪刀修剪、用于芯吸流体（例如，用于微流体应用）并通过焚烧处理。纸基电子电路薄且重量轻;它们应可用于消费电子和包装中的应用、用于军事和国土安全中的一次性系统、用于医学感测或低成本便携式诊断中的应用、用于纸基微机电系统以及用于涉及纺织品的应用。
This paper describes several low-cost methods for fabricating flexible electronic circuits on paper. The circuits comprise i) metallic wires (e.g., tin or zinc) that are deposited on the substrate by evaporation, sputtering, or airbrushing, and ii) discrete surface-mountable electronic components that are fastened with conductive adhesive directly to the wires. These electronic circuits-like conventional printed circuit boards-can be produced with electronic components that connect on both sides of the substrate. Unlike printed circuit boards made from fiberglass, ceramics, or polyimides however, paper can be folded and creased (repeatedly), shaped to form three- dimensional structures, trimmed using scissors, used to wick fluids (e.g., for microfluidic applications) and disposed of by incineration. Paper-based electronic circuits are thin and lightweight; they should be useful for applications in consumer electronics and packaging, for disposable systems for uses in the military and homeland security, for applications in medical sensing or low-cost portable diagnostics, for paper-based microelectromechanical systems, and for applications involving textiles.
