    Abstract: The microelectromechanical component (1) is implemented on a semiconductor-material substrate (10) and comprises two input terminals (7,8), two output terminals (26,27), an input metallic coil (2) connected to the input terminals and generating a magnetic field when carrying an electric current, a mobile part (3) connected to the substrate (10) by at least one deformable portion and comprising pads (11,12) made of ferromagnetic material, and an output part (4) forming a magnetic sensor connected to the output terminals and capable of generating an electric signal which is variable as a function of the displacement of the mobile part (3). The mobile part (3) can be displaced by the effect of a force acting on the pad (11) due to the magnetic field generated by the input coil (2). The input metallic coil (2) is of type solenoid, as in the first and the second embodiments, and of type planar spiral as in in the third embodiment. The mobile part (3) is laid out along the axis (9) of the input solenoid (2) and comprises two pads (11,12) separated by a longitudinal beam (14). Each pad (11,12) is connected to a pad (16,17) fixed on the substrate (10) by the intermediary of a set of beams, transversal beams (18,19,20,21) and longitudinal beams (23,24). The longitudinal beams (23,24) are connected to the fixed pads (16,17) by the intermediary of pairs of transversal portions joined to the fixed pads (16,17). The pads (11,12) are made of ferromagnetically soft material which becomes magnetized by the effect of magnetic field generated by the input coil, or made of ferromagnetically hard material forming permanent magnets. The first pad (11) is subjected to the force due to the magnetic field generated by the input coil (2), and the second spiral, as in the third embodiment. The output part in the second embodiment is a magnetic sensor from the group comprising the Hall effect sensor, the flux magnetometer, the magneto-resistances, the magneto-diodes, and the magneto-inductive sensors.

    Abstract: The micro-inductance or micro-transformer has a metallic coil with a magnetic core (4) having a ferromagnetic material strip (12). The center has a supplementary strip (13) in ferromagnetic material with a separation layer (14) in non-magnetic material. The non-magnetic material thickness is such that the two ferromagnetic strips are coupled anti-ferromagnetically.
