Abstract
An acceleration sensor has a mass movably linked to a peripheral attachment section to which at least one stopper is attached to stop the motion of the mass in a certain direction. In the absence of acceleration, the mass rests at a distance from a first surface of the stopper. A quantity of a curable elastic adhesive on a second surface of the stopper absorbs impact of the mass on the first surface, enabling the acceleration sensor to survive mechanical shock. The curable elastic adhesive may adhere to the cover of a package in which the acceleration sensor is enclosed. The curable elastic adhesive may be applied as a drop or swath from a dispenser, which simplifies the manufacturing process and reduces the manufacturing cost.
