Abstract :
We propose a novel MEMS shock sensor based on the notion of bistability. A moving mass induces the transition of a beam from a first stable configuration to a second stable configuration when a given acceleration threshold is reached. The new device has been designed, analysed numerically and tested with encouraging results.
