A flexible three-dimensional porous graphene foam-based supercapacitor (GFSC) is presented here for energy storage applications. With a novel layered structure of highly conductive electrodes (graphene-Ag epoxy–graphene foam), forming an electrochemical double layer, the GFSC exhibits excellent and supercapacitive performance. At current density 0.67 mA cm−2, GFSCs show performance with areal capacitance (38 mF cm−2) about three times higher than values reported carbon-based SCs. The...
In this work, we present a potentiometric pH sensor on textile substrate for wearable applications.
