title: Strain sensor using twisted optical fibers.
abstract: A novel sensor using twisted optical fibers is proposed to detect distributed tensile strain. This sensor converts tensile strain to optical loss. The relation between tensile strain and optical loss is modeled and experimentally confirmed for uniform tensile strain.
