ABSTRACT:
A thermal detector comprising a sensitive material having at least one electrical property of which varies with temperature; an electromagnetic radiation absorber which is in contact with the sensitive material; a substrate providing the function of support; and electrically conductive elements providing electrical continuity between sensitive material and substrate. The sensitive material is wholly or partly in the form of a sheet extending in a direction which is essentially perpendicular to the plane of the substrate. The sensitive material is suspended above the substrate by the absorber which is fixed to the sensitive material in the upper region of the sheet. The absorber is suspended by fixing means which is mechanically connected to the substrate.
