  • Publication number: 20240181727
    Abstract: A method of manufacturing a composite material including at least one ply integrating at least one electronic element situated at the surface of the ply. Also, materials obtained thereof and devices including such materials. The method includes: a) preparing or providing a first substrate having at least one layer; b) applying at least one electronic element onto a face of the first substrate; c) at least partially impregnating the so-obtained product within an impregnation material to form a matrix incorporating the at least one electronic element and the first substrate; d) preparing or providing an impregnable second substrate, the second substrate being placed on top of the impregnated at least one electronic element so that the at least one electronic element is interposed between the first substrate and the second substrate; e) removing the first substrate from the impregnated product obtained; and f) recovering the composite material.

  • Publication number: 20080134759
    Abstract: The invention concerns a sensor for detecting and/or measuring concentration of electric charges contained in an atmosphere. The sensor comprises a field-effect transistor structure including a bridge, which forms a gate and is suspended above an active layer located between drain and source regions. A gate voltage having a specific value is applied on the bridge. A so-called air gap region is included between the bridge and the active layer or an insulating layer deposited on said active layer, and has a specific height. An electric field (E), defined as the ratio between the gate voltage and air gap height, is generated in the air gap. The electric field generated in the air gap has a value not less than a specific threshold, sufficiently important for the electric field (E) to influence the distribution of electric charges contained in the atmosphere and present in the air gap, and to enable high sensitivity of the sensor to be achieved through accumulation of the electric charges on the active layer.
