Abstract: A method for the assembly of a metal part and a ceramic part, including the following steps: supplying a solid ceramic part of the alumina type; supplying a solid metal part, the metal being selected from platinum and tantalum, or an alloy including a majority of one of these metals; depositing at least one layer, called interface layer, on at least one of the solid parts, the interface layer containing magnesium oxide; bringing into contact the solid metal part and the solid ceramic part such that the interface layer is located between the solid parts; and hot densification under pressure of the solid parts brought into contact, to create a close bond between the solid parts and form a spinel from the interface layer. An electrical device, such as a capacitive sensor having a sensitive part produced according to the present method, is also provided.

Abstract: An appliance includes: at least one measurement electrode, for detecting at least one object in a detection zone, by detecting a signal with respect to a coupling capacitance between the object and said the at least one measurement electrode; at least one capacitive detection electronics, connected to the at least one measurement electrode, and an electric line, having at least one electric wire, in the detection zone; the appliance also including a signal conditioner, applying to at least a portion of the electric line, an alternating electrical potential (VG), called guard potential, identical to the detection potential at the detection frequency. The appliance can be a robot, in particular a robotized arm, equipped with an electric line providing a power supply to a component part of the robot.

Abstract: A device for detecting an object with respect to a detection surface including: a measurement electrode; at least one guard electrode, at the same alternating potential as the measurement electrode; at least one module for measuring a first signal with respect to the capacitance (Ceo), called electrode-object capacitance, formed between said measurement electrode and said object; and at least one electrode, called polarization electrode, placed opposite the object, and polarized at the ground potential (G) so as to polarize the object by capacitive coupling.
