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.
