  • Patent number: 10720298
    Abstract: A vacuum electron tube comprises at least one electron-emitting cathode and at least one anode arranged in a vacuum chamber, the cathode having a planar structure comprising a substrate comprising a conductive material, a plurality of nanotube or nanowire elements electrically insulated from the substrate, the longitudinal axis of the nanotube or nanowire elements substantially parallel to the plane of the substrate, and at least one first connector electrically linked to at least one nanotube or nanowire element so as to be able to apply a first electrical potential to the nanowire or nanotube element.

  • Patent number: 10014150
    Abstract: An x-ray generator tube comprises a vacuum chamber with a cathode and an anode, the cathode and anode placed in the vacuum chamber, the cathode emits an electron beam in the direction of the anode, the anode includes a target emitting x-rays when it is struck by the electron beam, and the x-rays propagate out of the vacuum chamber by passing through the wall of the chamber via a diamond-based transmission window. According to the invention, a diamond-based x-ray sensor is integrated into the diamond-based transmission window.

  • Publication number: 20160287113
    Abstract: A microelectrode (2) for neural interfacing applications comprises a first substrate layer (4), a second attachment layer (6), and a third layer (8) forming the active part of the electrode (2) of which the material consists of synthetic diamond made in electrically conductive by doping with atoms chosen from boron, nitrogen and phosphorus atoms. The material of the third layer (8) is a textured material that comprises a compact assembly, in the form of a brush, of tubes (26) each comprising, in the form of at in least one peripheral outer layer, polycrystalline diamond made electrically conductive by doping. The tubes (26) are separated from each other at the first fixed ends (28) of same and project the free ends (30) of same away from the first and second layers (4, 6) in a direction that is substantially vertical relative to the extension plane (20) of the second layer (6). A method for producing said microelectrode is also described.
