1. IntroductionMultifunctional flexible sensors are gaining more and more importance these days due to applications in the automotive, aerospace, bio, and structural health, marine, and energy sectors [1,2,3,4]. Strain sensors can be made from different materials like metals and polymers with different fillers. Polymers are intrinsically poor in electrical and thermal conductivity and require conductive fillers to enhance those properties for sensing applications.
