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: An appliance includes: at least one capacitive measurement electrode; at least one capacitive detection electronics; and an electric line, having at least one electric wire, in the detection zone; the appliance also having at least one spacer structure for distancing the electric line between: a minimum distance (Dmin) corresponding to the distance beyond which a reference electric line generates a coupling capacitance with the at least one measurement electrode, less than a predetermined threshold capacitance; and a maximum distance (Dmax) corresponding to the distance beyond which a reference object generates a coupling capacitance with the at least one measurement electrode, less than the threshold capacitance.

Abstract: A casing element for a robot, the casing element including: at least one capacitive electrode, termed a measurement electrode, intended to be biased to a first AC electric potential that is different from a ground potential, at a working frequency; at least one electrode, termed a guard electrode, arranged beneath the at least one measurement electrode and intended to be biased to an AC electric potential, termed the guard potential, that is identical or substantially identical to the first potential at the working frequency; and —at least one dielectric layer, termed a central dielectric layer, arranged between the at least one measurement electrode and the at least one guard electrode. A robot is also provided with at least such a casing element.
