    Abstract: The invention mainly concerns a capacitive device comprising at least first (2) and second (4) combs, respectively provided with interdigital fingers, adapted to be mobile relative to each other depending on the closing-spacing apart of the axes of the fingers, at least one finger of the first comb (2) including a surface opposite a surface of a finger of the second comb (4). The invention is characterized in that the axis of the finger of the first comb and the axis of the finger of the second comb are inclined relative to a plane orthogonal to the first direction (X) of displacement of the combs, the plane being defined by second (Y) and third (Z) directions perpendicular to the direction (X), and mutually perpendicular.
