摘要： An electrostatically servo-controlled pendular micro-sensor includes a pendular element disposed so as to respond to a force representative of a physical quantity to be measured. To avoid the drifts affecting the stability of the micro-sensor, generated by the existence of unstable parasitic voltages that impair the voltages provided by a system servo-controlling the pendular element, the electrostatic forces generated to draw back the pendular element through servo-control voltages have a zero mean value. The control voltages are periodic voltages or series of electric signals of equal durations, each having, preferably, a zero mean value.

摘要： A resonator microaccelerometer sensitive to accelerations along a first direction is formed from a thin plate whose plane comprises the first direction and a second direction perpendicular to the first direction and that is orthogonal with a third direction. The microaccelerometer comprises a fixed frame; a seismic mass; two hanging legs; and two resonator beams. The hanging legs extend substantially along the second direction, each leg being directed toward the center of gravity of the mass, symmetrically with respect to this center; the resonator beams are parallel, but non collinear, and are symmetrical with respect to the center of gravity of the mass.

摘要： A microgyrometer for detecting a rotation about a first direction comprises a plate that is orthogonal to the first direction, suspended to a fixed frame and excited at its resonance frequency along a second direction perpendicular to the first direction. A rotation about the first direction causes the plate to vibrate about a third direction orthogonal to the first two directions. The plate comprises teeth extending respectively along the second and third directions and engaging, without contact, in grooves integral with the frame. Each tooth carries lateral metallizations which constitute capacitors with facing metallizations of the grooves.
