<p>A magnetoelastic device (10) for providing a useful electric signal, which includes a unitary ferromagnetic element (12) having at least first and second generally planar substrates (20 and 22), at least one of the substrates being formed of ferromagnetic material, and wherein the substrates have different magnetically inductive association with the ferromagnetic element, operative, in response to a force applied thereto, which may or may not cause a displacement thereof, to provide a useful electrical signal.</p> |
