Nano zinc oxide/graphene-polymer composite materials with superior flexibility, high gauge factor and wide measurement range have been synthesized using hydrothermal, electrospinning and solvothermal methods. Mechanical, thermal, structural, morphological and piezoelectric properties of these materials have been studied in detail. The composites thus synthesized have been used to fabricate strain sensors after deposition of electrodes and were finally packaged with a thin polymeric layer for protection from mechanical wear and environmental damage. Sensors were flexible and possessed high sensitivity, linearity and reproducibility.
