A sensorized mat structure comprising: - a support base; - a plurality of sensors distributed on said support base adapted to generate respective measurement signals when they are subjected to a load bearing on said sensorized mat structure; - a control unit associated with said plurality of sensors configured to analyse and/or transmit said measurement signals to a remote unit; - a supply unit arranged to supply said plurality of sensors and said control unit; wherein each sensor comprises a cell with deformable box-like shape, and wherein said plurality of sensors is arranged on said support base so that said cells are adjacent with respect to each other, each of said cells comprising: - a support wall, opposite, in use, to said support base, said support wall arranged to receive said load, - a plurality of deformable side walls, said plurality of side walls and said support wall, in use, defining with said support base a housing; - at least one emitter of a light source and at least one photosensitive detector in said housing, said photosensitive detector configured to measure a changing light intensity collected from said emitter owing to the deformation of each cell when it is subjected to said load; wherein said cells are separated from each other by a predetermined separation space (s) in such a way that, when said support wall of each cell is subjected to said load, said side walls change their shape and are compressed towards said support base and while expanding laterally occupy a deformation space less than said separation space, so that adjacent cells do not touch each other; wherein said cells have a truncated pyramid-structure and define a matrix of cells, in such a way that: - said truncated pyramid structure is stiff with respect to tangential loads bearing on said side walls, and deformable with respect to normal loads bearing on said support wall; - said truncated pyramid structure in combination with said sensors allows that said measurement signals have a broad dynamic range that is high enough to be directly transmitted and analysed by said control unit; wherein each truncated pyramid cell having a stepped portion, wherein: - stepped portions of adjacent truncated pyramid cells are substantially adjacent to each other; - a minimum separation space (Smin) is defined at said stepped portion, and a maximum separation space (Smax) is defined at said support wall; and wherein each of said cells comprises: - said emitter of a light source; - said photosensitive detector arranged opposite said emitter; - a separation element located between said emitter and said photosensitive detector and arranged to move from a rest configuration, in which said cell is not subject to said load and all the light emitted by said emitter is collected by said photosensitive detector, to a bearing configuration, in which said separation element is lowered proportionally to said load and is located between said emitter and said photosensitive detector partially masking the light directed towards said photosensitive detector, proportionally to said load. - a support base;
