Synthesis of high-stretchable and compressible conductive double-networkhydrogels based on gelatin and polyacrylamide

Herein, we report a multifunctional nanocomposite hydrogel with outstanding stretchability, selfadhesive,fatigue resistance, and electrical conductivity by adding Ag nanoparticle-coated grapheneoxide (Ag/TA@GO)-based nanocomplexes into a polyacrylamide (PAM)/gelatin hydrogel matrix.This Ag/TA@GO-PAM nanocomposite hydrogel shows an ultrahigh stretchability of ۱۲۰۰% andexcellent conductivity. In addition, the strain sensors assembled by hydrogels accurately monitoredthe signals of human motions with good strain sensing durability. It is expected that the as-preparedhydrogels have the potential to be applied in the fields of wearable devices
