Patent ID: 7405403

Claim:
A bolometric detector for electromagnetic radiation comprising: a sensitive part or membrane comprising: one or more layers of a sensitive material, the resistivity of which varies with temperature; first electric conductor elements in electrical continuity with readout circuit associated with the bolometric detector and acting, on the one hand, as electrodes for said detector and, for this purpose, being in contact with said sensitive material and, on the other hand, acting as an electromagnetic radiation absorber; second electric conductor elements at a floating potential acting only as an electromagnetic radiation absorber; at least one support area for the sensitive part fulfilling the function of positioning said sensitive part and electric conductor in relation to said readout circuit; at least one thermal isolation structure electrically and mechanically linking each support area to the sensitive part; characterised in that the conductor elements are distributed as two crossed, superimposed networks of conductive tracks, the first of the two networks comprising all said first conductor elements.
