The persistence length of semiflexible polymers and one-dimensional fluid membranes is obtained from the renormalization their bending rigidity. renormalized rigidity calculated using an exact real-space functional group transformation based on a mapping to Heisenberg model. vanishes exponentially at large scales its asymptotic behaviour used define length. For polymers, our result agrees with tangent correlation functions. Our definition differs one commonly for membranes, which perturbative
