The invention relates to a pixel matrix of a thermal pattern sensor comprising several rows and several columns of pixels, said matrix comprising: 11. A pixel matrix of a thermal pattern sensor () , comprising several rows and several columns of pixels , said matrix comprising:{'b': 10', '20', '30', '20', '10', '30', '10, 'sub': 1', '2', '3', '4', 'N', '1', '2', '3', '4', 'N, 'an active thermal element (, , ) formed by a thermosensitive material () disposed between a lower layer (, c, c, c, c, c) and an upper layer (, Es), the lower layer (, c, c, c, c, c) being constituted by a plurality of first tracks made of electrically conductive material and extending along a first direction, said first tracks forming pixel columns;'}{'b': 50', '10', '20', '30', '1', '2', '3', '4', '5', '6', '1', '2', '3', '4', '5', '6', '1', '2', '3', '4', '5', '6', '1', '2', '3', '4', '5', '6', '1', '2', '3', '4', '5', '6', '1', '2', '3', '4', '5', '6', '1', '2', '3', '4', '5', '6, 'a heating element (), disposed on the active thermal element (, , ) and forming a serpentine path, said heating element being constituted by a plurality of second tracks (L, L, L, L, L, L) made of electrically conductive material and is also constituted by connecting segments (w, w, w, w, w, w) made of electrically conductive material connected to the ends of the second tracks (L, L, L, L, L, L), the connecting segments connecting second tracks (L, L, L, L, L, L) to one another, said second tracks (L, L, L, L, L, L) extending in a second direction different from the first direction and forming lines of pixels, the second tracks being connected except for the first and last second tracks (L, L, L, L, L, L), by their respective ends to one of the ends of a second preceding track and a second following track by way of said connecting segments (w, w, w, w, w, w), the first and last second tracks each having a free end connected to a connecting segment.'}2. The matrix as claimed in claim 1 , wherein the second ...
