Publication number: 20160265916Abstract: A micromechanical sensor for measuring z-axis angular rate includes a substrate defining a substrate plane and a z-axis perpendicular to the substrate plane. A first vibratory structure has a first shuttle-mass and a first proof-mass coupled to the first shuttle-mass by a first sense-mode spring. There is a second vibratory structure in a mirror-symmetrical setup (excepting the electrodes). First and second suspension structures suspend the first and second shuttle-masses above the substrate flexibly in drive-mode direction. Both shuttle-masses are suspended above the substrate for movement at least in drive-mode direction, wherein drive-mode direction and sense-mode direction are parallel to the substrate plane. Both vibratory structures are elastically coupled to each other.Type: ApplicationFiled: December 11, 2014Publication date: September 15, 2016Inventors: Christophe Kergueris, Luca Ribetto, Riccardo Signoretti

Publication number: 20150316378Abstract: A micromechanical sensor device for measuring angular z-axis motion comprises two vibratory structures each having at least one proof mass. A suspension structure maintains the two vibratory structures in a mobile suspended position above the substrate for movement parallel to the substrate plane in drive-mode (x-axis) direction and in sense-mode direction (y-axis). A coupling support structure connects the coupling structure to an anchor structure and enables a rotational swinging movement of the coupling structure, the rotational swinging movement having an axis of rotation that is perpendicular to the substrate plane. Each of the vibratory structures comprises at least one shuttle mass coupled to the at least one proof mass by sense-mode springs, which are more flexible in sense-mode direction than in drive-mode direction (x), for activating a vibration movement of each vibratory structure.Type: ApplicationFiled: December 9, 2013Publication date: November 5, 2015Applicant: TRONICS MICROSYSTEMS S.A.Inventors: Christophe KERGUERIS, Olivier GIGAN, Christian PISELLA, Yongjun YANG, Bo LI, Shujing XU
