Abstract: An acceleration-triggered or shock-triggered, smart, tunable MEMS switch that may function as both a classic accelerometer and an acceleration threshold detector. A parallel element MEMS device has a stationary and a movable element forming a capacitor. Varying acceleration moves the movable member with respect to the stationary member, thereby changing the capacitance of the device. The capacitance varying may be used, in cooperation with appropriate circuitry, to provide a signal representative of instantaneous acceleration. By applying a biasing voltage, the movable element may be positioned in a predetermined fashion such that acceleration of a predetermined magnitude causes the movable element to pull in (snap down). The movable and stationary elements may function as a switch such that when the predetermined acceleration or shock level occurs, electrodes close, a current flows between the elements so that an external device such as an air bag may be activated.

Abstract translation: 加速度触发或触发触发的智能可调谐MEMS开关，其可以用作经典加速度计和加速度阈值检测器。 并联元件MEMS器件具有形成电容器的静止元件和可动元件。 不同的加速度使可动构件相对于静止构件移动，从而改变装置的电容。 可以与适当的电路配合使用电容变化来提供代表瞬时加速度的信号。 通过施加偏压电压，可移动元件可以以预定方式定位，使得预定幅度的加速度使得可移动元件拉入（向下）。 可移动和固定元件可以用作开关，使得当预定的加速度或冲击水平发生时，电极闭合，电流在元件之间流动，使得诸如气囊的外部装置可被启动。
