Transient electronics are emerging as a promising class of devices designed to disappear after a defined operational period, addressing growing concerns over sustainability and long-term biocompatibility. Built from biodegradable materials that undergo hydrolysis or enzymatic degradation, these systems are particularly well suited for temporary implantable applications, such as neural monitors, wireless stimulators, and drug delivery vehicles, as well as environmentally benign electronics for soil or aquatic disposal. Despite their potential, key challenges remain in expanding the material set for diverse functionalities, achieving high-density integration for advanced operations, and enabling precise lifetime control through strategies such as protective encapsulation. This Perspective outlines critical opportunities and technical directions to guide the development of next-generation transient electronic systems.
瞬态电子器件正成为一类很有前景的器件，这类器件被设计成在规定的运行期后消失，以应对人们对可持续性和长期生物相容性日益增长的担忧。这些系统由可发生水解或酶促降解的可生物降解材料制成，特别适合用于临时植入应用，如神经监测器、无线刺激器和药物输送载体，以及用于土壤或水体处置的环境友好型电子产品。尽管它们具有潜力，但在扩大具有多种功能的材料种类、实现用于先进操作的高密度集成以及通过保护性封装等策略实现精确的寿命控制方面，仍然存在关键挑战。本观点概述了指导下一代瞬态电子系统发展的关键机遇和技术方向。
