瞬态电子器件全部由可降解材料组成，当器件完成指定功能或废弃之后，可在外界的刺激下短时间内部分消失或全部降解。通过先进的加工工艺和功能优异的特种材料，瞬态电子器件的性能可与传统电子器件相媲美，并对传统器件功能形成补充，将应用范围扩展到环保、可降解医疗设备以及电子安全器件等前沿领域。本文从瞬态可降解材料、降解方式、加工工艺、功能瞬态器件等方面介绍2017年瞬态电子技术的主要研究进展，并对瞬态电子领域的未来发展作一展望。
Transient electronics, fabricated by degradable materials, can dissolve in natural environments after completing the default task. The corresponding decomposition products are biologically safe, offering an efficient approach to solving the pollution caused by electronicwastes. Transient electronics can compare favorably with the traditional devices through advanced fabrication technology in terms of performance, exhibiting promising applications in fields of environmental protection, medical equipment and information security. In this paper, we summarize the progresses in transient electronics in 2017, including degradable materials, degradable procedures, fabrication technology and transient devices.
