Abstract:
1. A strain sensor comprising: (a) at least one conductive electrospun fiber portion containing therein or thereon at least one conductive compound, wherein the at least one conductive electrospun fiber portion is mounted on a substrate, or freely suspended, via at least two contact points; (b) at least one electric current and/or voltage sensing device that is designed to provide an electric current and/or voltage to the at least one conductive electrospun fiber portion via at least two appropriately spaced contact points; and (c) at least one electric current and/or voltage calculation and/or observation means, wherein the electric current and/or voltage sensing device is designed to monitor the electric current and/or voltage through the at least one conductive electrospun portion, and in conjunction with the at least one electric current and/or voltage calculation and/or observation means permits one to monitor the strain that exists in the at least one conductive electrospun fiber portion of the strain sensor.
