ABSTRACT:
The Resettable Latching MEMS Shock Sensor provides the capability of recording external shock extremes without consuming electrical power. The device incorporates a shock sensitive suspended proof mass, spring-loaded contacts, latches, and actuators for device reset. The device can be designed, hardwired, or programmed to trigger at various shock levels. The device can be fabricated in a simple micromachining process that allows its size to be miniaturized for embedded and portable applications. During operation, the device consumes no quiescent power. The device can be configured to close a circuit, switch an interrupt signal, or switch some other electrical trigger signal between devices at the time of a shock extreme being reached, or it can be configured to latch and be polled at some time after the shock limit has occurred.
