Abstract

Impact or acceleration sensor, which contains a liquid droplet and is designed such that the position and/or distribution of the liquid indicates whether an impact or any other acceleration of a predetermined minimum magnitude has occurred, includes: first and second foils, a cavity disposed between the foil faces of the foils and at least one retaining structure disposed on the foil face of the first and/or second foil and functions to maintain the liquid in a predetermined first sub-volume of the cavity. The retaining structure is a region of the first and/or second foil formed as a local elevation, depression or irregularity of the foil face, which forms a passable barrier for the wetting and/or contacting of the first and/or second foil by the liquid and defines an area piece of the foil face of the first and/or second foil corresponding to the first sub-volume.
