瞬态电子学代表了一类新兴的技术，其利用能够以编程的速率或时间以受控的方式物理消失或分解的材料和/或设备构造。无机半导体纳米材料如硅纳米膜/纳米带为晶体管中的有源元件提供了有吸引力的选择;二极管和整个系统的其他基本组件，通过水解在生物流体或地下水中完全溶解。我们在这里描述材料，力学和设计布局，以实现这种类型的技术在可拉伸配置与可生物降解的弹性体的基板/封装层：实验和理论结果阐明了大应变变形下的机械性能。互补金属氧化物半导体逆变器和各个晶体管的电路特性在各种水平的应用负载验证的设计策略。生物传感器的例子证明了在生物医学应用中可拉伸的瞬时装置的可能性。
Transient electronics represents an emerging class of technology that exploits materials and/or device constructs that are capable of physically disappearing or disintegrating in a controlled manner at programmed rates or times. Inorganic semiconductor nanomaterials such as silicon nanomembranes/nanoribbons provide attractive choices for active elements in transistors;. diodes and other essential components of overall systems that dissolve completely by hydrolysis in biofluids or groundwater. We describe here materials, mechanics, and design layouts to achieve this type of technology in stretchable configurations with biodegradable elastomers for substrate/encapsulation layers: Experimental and theoretical results illuminate the mechanical properties under large strain deformation. Circuit characterization of complementary metal-oxide-semiconductor inverters and individual transistors under various levels Of applied loads validates the design strategies. Examples of biosensors demonstrate possibilities for stretchable, transient devices in biomedical applications.
