1. Strain sensors wherein said strain sensor is formed in a sheet shape from composites, and said sheet shape strain sensor is fixed to an exterior of iron and iron-concrete structural products, said composites consisting of polymers and individual conductive particles dispersed in said polymers, and a strain of said composites causes changes in a distance between said conductive particles and a corresponding change in electric resistance of said composites so as to recognize values of said strain.
