Screen-printed technology has helped considerably to the development of portable electrochemical sensors since it provides miniaturized but robust and user-friendly electrodes. Moreover, this technology allows to obtain very versatile transducers, not only regarding their design, but also their ease of modification. Therefore, in the last decades, the use of screen-printed electrodes (SPEs) has exponentially increased, with ceramic as the main substrate. However, with the growing interest in the use of cheap and widely available materials as the basis of analytical devices, paper or other low-cost flat materials have become common substrates for SPEs. Thus, in this revision, a comprehensive overview on paper-based SPEs used for analytical proposes is provided. A great variety of designs is reported, together with several examples to illustrate the main applications.
丝网印刷技术在便携式电化学传感器的发展中起到了重要作用，因为它提供了小型化但坚固耐用且用户友好的电极。此外，这项技术可以获得非常多样化的传感器，不仅在设计方面，而且在易于修改方面也是如此。因此，在过去几十年中，丝网印刷电极（SPE）的使用呈指数级增长，以陶瓷为主要基底。然而，随着人们对使用廉价且广泛可用的材料作为分析设备基础的兴趣日益浓厚，纸张或其他低成本平面材料已成为 SPE 的常见基底。因此，在本次综述中，提供了用于分析目的的基于纸张的 SPE 的全面概述。报告了各种各样的设计，并提供了几个示例来说明主要应用。
