Reduced graphene oxide-based highly sensitive pressure sensor for wearable electronics via an ordered structure and enhanced interlayer interaction mechanism.

ABSTRACT: Compressible carbon materials have promising applications in various wearable devices. However, it is still difficult to prepare a carbon material with superior mechanical properties, stable strain-electrical signal response, and high linear sensitivity. In this study, a compressible and conductive carbon aerogel with excellent properties is obtained by designing an ordered wavy layered structure with enhanced interactions between carbon layers. Bidirectional freezing is used to produce a wavy layered structure. Cellulose nanocrystals (CNC) and lignin play important roles in enhancing the interactions between reduced graphene oxide (rGO) layers. Due to the design of the carbon aerogel structure and interlayer interactions, the prepared carbon aerogel exhibits supercompressibility (up to 99
