Abstract
A deformation detecting device includes weft yarns and warp yarns woven together. At least some of the weft yarns, or some weft yarns, and some warp yarns, are electrically conductive. The weft yarns include a flocking made up of non-electrically conductive fibers protruding substantially radially from the weft yarns. The electrically conductive yarns are connected to conductive ends for applying an electrical voltage, such that yarns that are connected to conductive ends with different polarities define respective plates of a capacitive sensor, while the fibers of the flocking of the weft yarns define a dielectric material interposed between the capacitive sensor plates. The device comprises an electronic control and processing unit configured to detect a deformation of the fabric based on a capacitance variation of the capacitive sensor.
