Abstract:
A displacement transducer comprising:a substrate; an element suspended from the substrate and supported by it at one or more anchor points, wherein the element is displaceable responsive to a force; a Hall junction including a current path for supporting a flow of current; a miniaturized magnet, one or the other of the magnet and Hall junction supported by the element, and the other of the magnet and Hall junction stationary with respect to the substrate, wherein the magnet has an edge, and the Hall junction has a center spaced from the magnet edge by a sub-micron gap; wherein relative displacement between the element and the Hall junction by an amount x induces formation of a signal at the Hall junction representative of the amount x of the relative displacement between the element and the Hall junction; and one or more signal lines coupled to the Hall junction for providing the signal representative of the amount x of the relative displacement between the element and the Hall junction.
