    • A MEMS resonant accelerometer is disclosed, having: a proof mass coupled to a first anchoring region via a first elastic element so as to be free to move along a sensing axis in response to an external acceleration; and a first resonant element mechanically coupled to the proof mass through the first elastic element so as to be subject to a first axial stress when the proof mass moves along the sensing axis and thus to a first variation of a resonant frequency. The MEMS resonant accelerometer is further provided with a second resonant element mechanically coupled to the proof mass through a second elastic element so as to be subject to a second axial stress when the proof mass moves along the sensing axis, substantially opposite to the first axial stress, and thus to a second variation of a resonant frequency, opposite to the first variation.
    • 公开了一种MEMS谐振加速度计,其具有:经由第一弹性元件耦合到第一锚定区域的检测质量,以便响应于外部加速度沿感测轴线自由移动; 以及第一谐振元件,其通过所述第一弹性元件机械耦合到所述检验质量块,以便当所述检测质量沿着所述感测轴线移动并且因此达到谐振频率的第一变化时,经受第一轴向应力。 MEMS谐振加速度计进一步设置有第二谐振元件,其通过第二弹性元件机械耦合到校准物质,以便当检测质量沿着感测轴线移动时受到第二轴向应力,基本上与第一轴向应力相反 ,从而达到与第一变化相反的谐振频率的第二变化。
