印刷电子技术作为一个新兴电子技术正在受到越来越广泛的关注。通过印刷方法制造的信息电子与光电子器件和系统具有大面积、柔性化、个性化、低成本、绿色环保等一系列优点。尽管印刷加工本身没有传统微纳米加工的高分辨率与高集成度，但上述优点足以使印刷电子在许多新应用领域发挥作用。本文对印刷电子定义、起源、发展历程及产业与技术现状进行了全面介绍，分析了印刷电子面临的挑战，并对印刷电子未来发展前景做了展望。
Printed electronics as a newly emerged electronics discipline has received increasing attention in recent years. Electronic and optoelectronic devices and systems fabricated by printing are of several distinctive advantages, such as large area, flexible, customizable, low cost and environmental friendly. Though printing's resolution is not as high as conventional microfabrication, the above advantages are enough to warrant many new applications. This article gives a comprehensive introduction of the definition of printed electronics, its origin and development history. Based on the author's own many years experience, the technology and commercialization challenges for printed electronics are analyzed. The future development trend is described. It is hoped that this article will give readers an overview of the new technology.
