Highly Conducting and Stretchable Double‐Network Hydrogel for Soft Bioelectronics

Abstract Conducting polymer hydrogels are promising materials in soft bioelectronics because of their tissue‐like mechanical properties and the capability of electrical interaction with tissues. However, it is challenging to balance electrical conductivity and mechanical stretchability: pure conducting polymer hydrogels are highly conductive, but they are brittle; while incorporating the conducting network with a soft network to form a double network can improve the stretchability, its electrical conductivity significantly decreases. Here, the problem is addressed by concentrating a poorly crosslinked precursor hydrogel with a high content ratio of the conducting polymer to achieve a densified double‐network…
