Abstract
A shock sensor includes: a supporting body; a bistable mechanism, configured to switch from a first stable mechanical configuration to a second stable mechanical configuration in response to an impact force applied along a detection axis and such as to supply to the bistable mechanism an amount of energy higher than a transition energy; and a detection device, coupled to the bistable mechanism and having a first state, when the bistable mechanism is in an initial stable mechanical configuration and a second state, after the bistable mechanism has made a transition from the initial stable mechanical configuration to a final stable mechanical configuration. The bistable mechanism includes at least one elastic element, constrained to the supporting body in at least two opposite peripheral regions and defining a first concavity in the first stable mechanical configuration and a second concavity, opposite to the first concavity, in the second stable mechanical configuration.
