Ultralow-CostGraphene/Fabric-Based Sensors: Characterizati on and Preliminary Results

Abstract

The significance of fabric sensors has been growing simultaneously with the impact of wearable sensing applications. Different types of fabrics have been employed to develop thin-film sensors for multiple applications. This article highlights the fabrication and implementation of polyester fabric/graphene-based sensors for strain and acoustic applications. Conductive composite structures were formed by dip-coating polyester fabric into aqueous graphene dispersions with defined cycles. These sensors were piezoresistive in nature, characterized and utilized to sense strain-induced tactile motion. Due to their vibrational nature, they were also deployed to detect acoustic signals, thus validating their potential for multifunctional strain-sensing applications. These results serve as a podium to develop flexible graphene/fabric-based sensors for multifunctional strain-induced applications.
