Conductive Hydrogel for Flexible Bioelectronic Device: Current Progress and Future Perspective

Advanced Functional Materials, Год журнала: 2023, Номер 34(1)

Опубликована: Сен. 19, 2023

Abstract Conductive hydrogels (CHs) for flexible bioelectronic devices have raised great attention due to their tunable mechanical performances, adhesion, anti‐swelling, and biocompatibility. This review summarizes the current development of conductive hydrogel‐based in aspect classifications applications. Firstly, are classified into two kinds according types conductivity: ionic electronic (hydrogel based on pure materials, introducing micro/nano‐materials). Secondly, applications device, like wearable (strain sensor, body fluid detector, serviced extreme environment), tissue engineering (skin, heart, nerve, muscle), other (bionic robot, cancer treatment), highly illustrated. Finally, a depth outlook is given, which aims promote this field future.
