Thanks to the advances in micromachining fabrication technologies and significant cost reduction due to mass production, miniature sensors of angular rate, or gyroscopes, found their way into the everyday life of every user of modern gadgets, such as smart phones, tablets or even wristwatches. Often without realising, many of us are carrying in our pockets fully equipped with all necessary sensors complete inertial navigation systems that not so long ago were available only for advanced vehicles in sea, land, air or space. Accelerometers and gyroscopes are found in specifications of any gadget supposed to react to user movements. And one of the most commonly used type of gyroscopes used to developed these systems is Coriolis vibratory gyroscope (CVG).

陀螺仪硬件自检：相关方法陀螺仪允许用户测试机械和电气部分。自检的代码在 InvenSense提供的 MotionApps™软件里面。如果没有使用 MotionApps™软件，请参阅下节(Obtaining the Gyroscope Factory Trim (FT) Value)。当自检启动，片上的电子设备就会启动相应的传感器。这次启动会使传感器的 proofmasses的距离相当于一个预定的科里奥利力（Coriolis force）。传感器的 Proof masses位移变换的结果将在输出信号中反映。输出信号用户可以在自检反馈看到。自检反馈（STR）定于如下：Self Test Response=Gyroscope Output with Self Test Enabled — Gyroscope Output with Self Test Disabled自检反馈通过反馈与出产的评估比较查找变换用于确定这部分通过还是自检失败
