Abstract
In order to implement two different sensitivities simultaneously in one component, in particular in an acceleration sensor having a substrate, at least one spring device, and at least one seismic mass, it is proposed that the spring device be designed for an intrinsically nonlinear behavior corresponding to a progressive spring characteristic curve, in which a greater acceleration is associated at least locally with a greater rigidity (spring constant).
