Abstract: The core-shell structured fiber-type strain sensor of the present disclosure, which includes a fibrous support forming a core and a multilayered shell layer formed on the fibrous support, exhibits improved strength and stiffness due to the core fiber, exhibits improved noise level due to an elastomer layer and allows manufacturing of a fiber-type sensor with improved linearity of measurement signals due to a sandwich-structured conductive layer, is advantageous in that stable strain measurement is possible without acting as a defect in a composite structure.
