A deformation detecting device comprising a multi-functional fabric (10) including weft yarns (T) and warp yarns (O) woven together. At least some of the weft yarns, or alternatively some weft yarns (T), and some warp yarns (O), are electrically conductive. The weft yarns (T) are provided with a flocking made up of non-electrically conductive fibers (F) protruding substantially radially from the weft yarns (T). The electrically conductive yarns are connected to conductive ends (P) for applying an electrical voltage, in such a way that yarns that are connected to conductive ends (P) with different polarities define respective plates (A1, A2) of a capacitive sensor (S), while the fibers (F) of the flocking of the weft yarns (T) define a dielectric material interposed between the capacitive sensor plates (A1, A2), The device comprises an electronic control and processing unit (E) connected to the conductive ends (P) and configured to detect a deformation of the fabric (10) on the basis of a detection of a capacitance variation of said capacitive sensor (S).
