Abstract: A microelectromechanical system switch includes a signal input line, a signal output line, a deformable conducting membrane electrically connected to the signal output line and including a contact dimple facing the signal input line, and an actuation electrode. The membrane has a planar round shape, with a radial opening in the direction of the signal input line, narrowing from the periphery towards the center of the membrane, the contact dimple being formed in the central region of the membrane, the actuation electrode has the same shape as the membrane, and the gap between the membrane, facing the actuation electrode, and the actuation electrode is an airgap only.

Abstract: Method for determining, in vitro, the cell aggressiveness grade of cancer cells or for detecting cancer stem cells in a cell sample originating from a solid tissue suspected of being cancerous, includes: a) dissociating the cell cluster constituting the sample into a suspension of whole and viable isolated cells, b) macroscopically sorting the cells to obtain homogeneous subpopulations, c) calibrating at least one microwave electromagnetic sensor resonating at its own resonance frequency, d) presenting the dissociated and sorted cells to the calibrated sensor, e) interrogating the sensor and determining its new resonance frequency having received the cells, f) calculating the variation in overall dielectric permittivity of the cells according to the variation in working frequency, which constitutes the electromagnetic signature of the cells. The macroscopic sorting is without prior labelling and is based on the intrinsic properties of the cells. A kit for implementing the method is also described.

Abstract: The invention relates to a frequency filter including a structure with, on one face, two extreme evanescent areas and at least one wave guide area between the evanescent areas. The at least one wave guide area and the evanescent areas form a single closed cavity. The single cavity is partitioned by at least two resonator elements that are embedded in the single cavity at placement areas and that contribute to delimiting the at least one wave guide area and the evanescent areas.

Abstract: A microcomponent which includes a capacitive component, of at least two elementary capacitors (C1, C2, C3, C4) which are connected in series. Each elementary capacitor is made up of two plates namely: a plate (10) fixed with respect to the rest of the microcomponent; and a second plate (12), part of which is capable of being displaced with respect to the first fixed plate (10) due to the effect of a control signal, so as to vary the value of the capacitance of the elementary capacitor C1. The control signals for the various elementary capacitors are generated independently so as to vary the overall capacitance of the capacitor by independent variation of the capacitances of each elementary capacitor.

Abstract: An elementary electrical resonator which includes a ribbon conductor forming a flat loop with at least one turn, the conductor having ends which form two parallel segments. The resonator further includes a conducting bridge which forms an arch straddling the two parallel segments of the ribbon conductor wherein opposing surfaces of the arch and the parallel segments form a capacitor. A part of the bridge is capable of being displaced with respect to the parallel segments under the action of a control signal so as to cause the capacitance of the capacitor and therefore the tuning frequency of the resonator to vary.
