Polymer-based flexible bioelectronics

Due to the mechanical mismatch between conventional rigid electronic devices and soft tissues at nature, a lot of interests have been attracted to develop flexible bioelectronics that work well both in vitro and in vivo. To this end, polymers that can be used for both key components and substrates are indispensable to achieve high performances such as high sensitivity and long-term stability for sensing applications. Here we will summarize the recent advances on the synthesis of a variety of polymers, the design of typical architectures and the integration of different functions for the flexible bioelectronic devices. The remaining challenges and promising directions are highlighted to provide inspirations for the future study on the emerging flexible bioelectronics at end. (C) 2019 Science China Press.
