Abstract: A method for acquisition and analysis of a multi-contact tactile sensor including a matrix of capture points and an electronic analysis circuit for controlling the acquisition and analysis of the matrix. The method includes acquisition of a sensor detection zone to determine a state of each of contact points of the detection zone and analysis of detection zone to deliver information as a function of an activation state of the contact points. The acquisition and the analysis are repeated iteratively. The acquisition is performed on a detection zone containing the activated contact points determined during a preceding analysis. The detection zone is smaller than the detection zone acquired during the preceding acquisition. The iteration is performed until a pre-determined spatial resolution is obtained. An electronic acquisition and analysis circuit and a multi-contact tactile sensor can implement such a method.
