Abstract: The inductive micro-device comprises a rectilinear solenoid winding comprising a plurality of disjointed rectangular turns each having predetermined dimensions. At least one of the dimensions of the turns is variable and is determined individually for each turn according to the position of the turn along the winding and to predetermined magnetic characteristics of the winding, in particular a homogeneous magnetic field and/or an optimum quality factor. Said variable dimension of the turns is chosen from the width, length, thickness, height of turn and the value of the gap between two adjacent turns.

Abstract: The magnetic device according to the invention is integrated on a substrate and comprises at least one element made of piezoelectric material associated with actuating electrodes, and at least one magnetic element able to deform under the stress of the piezoelectric material element. The device has the form of a beam movable with respect to the substrate, and comprises two transverse parts of predetermined width, along a reference longitudinal axis. The piezoelectric material element is formed by at least a part of a transverse part and each transverse part comprises a zone for mechanical anchoring on the substrate. The transverse parts are connected by at least one central branch, of predetermined width, on which the magnetic element is arranged.

Abstract: The coil comprises a plurality of non-joined turns, each turn comprising a rectangular bottom flat section in a bottom plane and a rectangular top flat section in a top plane and two rising sections. The turns fill almost all of the enveloping surface of the coil, a minimum isolating gap separating the adjacent turns. The top and bottom sections corresponding to one and the same turn are aligned with respect to one another and have a larger width than the width of the corresponding rising sections. The turns constitute a plurality of substantially parallel coil branches, rising sections of two adjacent branches arranged between the two adjacent branches being arranged alternately in a single plane.

Abstract: The closed magnetic core is designed for use for an integrated micro-inductor. The magnetic core has the form of a spiral preferably substantially rectangular spiral. The spiral comprises two ends joined to one another by a closing segment. The magnetic core can be formed by a plurality of branches and at least two branches can be arranged in different parallel planes. In addition, two branches can have different thicknesses. The magnetic core can comprise an air-gap.
