Integrating electronic applications with paper, placed next to or below printed images or graphics, can further expand the possible uses of paper substrates. Consuming paper as a substrate in the field of electronics can lead to significant innovations toward papertronics applications as paper comprises various advantages like being disposable, inexpensive, biodegradable, easy to handle, simple to use, and easily available. All of these advantages will definitely spur the advancement of the electronics field, but unfortunately, putting electronics on paper is not an easy task because, compared to plastics, the paper surface is not just rough but also porous. For example, in the case of lateral flow assay testing the sensor response is delayed if the pore size of the paper is enormous. This might be a disadvantage for most electrical devices printed directly on paper. Still, some methods make it compatible when fit with a rough, absorbent surface of the paper. Building electronic devices on a standard paper substrate have sparked much interest because of its lightweight, environmental friendliness, minimal cost, and simple fabrication. A slew of improvements have been achieved in recent years to make paper electronics perform better in various applications, including transistors, batteries, and displays. In addition, flexible electronics have gained much interest in human-machine interaction and wireless sensing. This review briefly examines the origins and fabrication of paper electronics and then moves on to applications and exciting possible paths for paper-based electronics.
将电子应用与纸张相结合，放置在印刷图像或图形旁边或下方，可以进一步拓展纸质基材的潜在用途。在电子领域将纸张用作基材，有望催生纸质电子应用的重大创新，因为纸张具有诸多优点，如可一次性使用、价格低廉、可生物降解、易于处理、使用简便且容易获取。所有这些优点必将推动电子领域的发展，但遗憾的是，在纸张上制作电子产品并非易事，因为与塑料相比，纸张表面不仅粗糙，而且多孔。例如，在横向流动分析测试中，如果纸张的孔径过大，传感器响应就会延迟。这对大多数直接印刷在纸张上的电子设备来说可能是个劣势。不过，一些方法能使其与纸张粗糙的吸水表面兼容。在标准纸质基材上制造电子设备因其重量轻、环保、成本低且制造简单而引发了广泛关注。近年来，为使纸质电子产品在包括晶体管、电池和显示器等各种应用中表现得更好，已取得了一系列进展。此外，柔性电子产品在人机交互和无线传感方面也备受关注。本文简要探讨了纸质电子学的起源与制造，接着介绍了其应用以及基于纸张的电子产品令人兴奋的可能发展方向。
