Claim Text:
1. A shock sensor comprising: a supporting body; a bistable mechanism configured to switch from a first configuration to a second configuration in response to a shock force that is applied to a detection axis and is greater than a threshold value, the bistable mechanism including an elastic element that is coupled to the supporting body by at least two peripheral regions the elastic element being independently stable in the first configuration and the second configuration and defining a first concavity in the first configuration and a second concavity, opposite to the first concavity, in the second configuration; an electrode capacitively coupled to the elastic element to form a capacitor; and a detection device coupled to the bistable mechanism, and having a first state when the bistable mechanism is in the first configuration, and a second state after the bistable mechanism has switched from the first configuration to the second configuration.
