Abstract
A sensor has a substrate in which a mechanically deformable area is formed. A first magnetostrictive multilayer sensor element and a second magnetostrictive multilayer sensor element are formed in the mechanically deformable area, wherein the first magnetostrictive multilayer sensor element and the second magnetostrictive multilayer sensor element are connected to each other and implemented such that when generating a mechanical deformation of the mechanically deformable area, the electric resistance of the first magnetostrictive multilayer sensor element changes in an opposite way to the electric resistance of the second magnetostrictive multilayer sensor element, or the electric resistance of the first magnetostrictive multilayer sensor element remains unchanged.
