Stretchable and fully degradable semiconductors for transient electronics
Electronics that can be stretched like human skin and feature skin-inspired functionalities are opening doors for remarkable opportunities in health and environmental monitoring, next-generation consumer products, and sustainability. Notably, degradability is an attractive attribute for applications on dynamic surfaces where manual recovery would be prohibitively difficult and expensive. A key component of such electronics is the development of a stretchable and degradable transistor with electrical performance independent of large mechanical stress. Herein, we demonstrate for the first time a material that simultaneously possesses three disparate attributes: semiconductivity, intrinsic stretchability, and full degradability. We show that we can design acid-labile semiconducting polymers to appropriately phase segregate within a biodegradable elastomer, yielding semiconducting nanofibers which concurrently enable controlled transience and strain-independent transistor mobilities. This fully degradable semiconductor represents a promising advance towards developing multifunctional materials for skin-inspired electronic devices that can address previously inaccessible challenges and in turn create new technologies.
