A capacitive or resistive tactile sensor having a conductive membrane, a flexible dielectric or weakly conductive sheet and a substrate having electrodes, and a method of manufacturing thereof. The flexible sheet has a first surface and an opposite second surface, the first surface and the second surface are uniformly distanced when at rest. The first surface is adapted to contact one of the conductive membrane or the substrate. The second surface is adapted to contact another one of the conductive membrane or the substrate. The body defines between the first and second surfaces, at a predetermined region, a plurality of laser ablated uniform cavities that are evenly distributed and operatively identical in order to provide a known compression index at the predetermined region of the flexible sheet. The substrate has uniformly distributed static pressure sensing electrodes and at least one uniformly spread dynamic pressure sensing electrode, which is located between the static pressure sensing electrodes, and is used for measuring a voltage or a current variation with the conductive membrane according to the deformation of the flexible sheet.
