    Abstract: The present invention relates to a multicontact tactile sensor (1) comprising a matrix formed of two transparent conducting layers, at least one exhibiting an array of fine conducting tracks, and a control circuit comprising a power supply for one of the layers and means for detecting the other layer, said sensor (1) having an operating mode of multicontact type (32) corresponding to a sweep of the supply to the lines of the corresponding layer, characterized in that it also comprises an operating mode of monocontact type (33) corresponding to a continuous and uniform supply over the whole of the sensor, each operating mode (32, 33) being activated as a function of the detection or nondetection of at least one contact.

    Abstract: The present invention relates to a multipoint touch sensor with active matrix comprising: - a matrix layer exhibiting NxM independent cells, each of the cells Px, y being linked to a row Lx and to a column Cy through a switching element, the rows Lx being common to all the cells Px, i, i lying between 1 and N, and the columns Cy being common to all the cells Pj, y, j lying between 1 and Q, Q being at most equal to M, an intermediate layer able to cause a local modification of the electrical properties of the cells situated under the tactile activation zone, said intermediate layer being placed between the active surface of the adjacent surface of the said Px, y, cells, - an upper activation layer allowing tactile interaction, - an electronic circuit sequentially controlling, for each set of cells Ca, b1-b2 with b2-b1 lying between 1 and Q, a first step of activating said cells Ca, b1-b2 followed by a second step of detecting the electrical properties of each cell Ca, b1-b2 individually so as to deliver an item of information representative of the zones activated by touch.
