Abstract
A device and method measure an acceleration of a moving body. The device contains a solid body having a moving part and an internal cavity capable of allowing for a free movement of the moving part. The internal cavity has at least one wall forming a sloping track, the sloping track having a surface allowing for the free movement of the moving part on the sloping track between an initial position at rest and a distant position spaced from the initial position situated at an end of the internal cavity and reachable by the moving part during a variation in acceleration. The moving part moving from the initial position to the distant position in the internal cavity under an effect of the acceleration of the moving body. At least one detector is provide and is capable of detecting a presence of the moving part at the distant position.
