This invention pertains to a low cost, low noise strain sensor based on a web of continuous core-shell nanofibers with conductive shell and mechanically robust core that can be attached or embedded on a variety objects for directional monitoring of static or dynamic changes in mechanical deformation and pressure. This is a low cost, highly sensitive strain sensor, with low noise and ease of integration for different applications from synthetic tactile skins, to vibrational and health monitoring.

Core-shell nanofiber textiles for strain sensing, and methods of their manufacture

A water vapor transport membrane comprises a nanofibrous layer disposed on a macroporous support layer, the nanofibrous layer coated with a water permeable polymer. A method for making a water vapor transport membrane comprises forming a nanofibrous layer on a macroporous support layer and applying a water permeable polymer to the nanofibrous layer. The water permeable polymer can be applied for so that the nanofibrous layer is substantially or partially filled with the water permeable polymer, or so that the coating forms a substantially continuous layer on one surface of the nanofibrous layer. In some embodiments of the method, the nanofibrous layer is formed by electro-spinning at least one polymer on at least one side of the porous support layer. In some embodiments, the support layer is formable and the method further comprises forming a three-dimensional structure from the water vapor transport membrane, for example, by compression molding, pleating or corrugating.
