Abstract: A composite fabric which is elastic and conductive and thus able to detect a user's limb and body movements includes a fabric layer and an elastic conductive layer of elastomer and conductive filler formed on the fabric layer. A resistance value and a strain increments of the fabric satisfy a relationship of RT=R+nε or RT=R+m enε, wherein ε denotes the strain increment, R denotes the resistance value when the strain increment is 0, and RT denotes the resistance value when deformed through the increments. The m and n are coefficients, being a whole number or a fraction. A user can immediately detect and know the movements of his limbs according to the resistance value of the elastic conductive composite fabric.
