Abstract:
A magnetic field sensor comprises a substrate and a moving part which is displaced when subjected to a Laplace force. There is a gauge for measuring the displacement of the moving part. There is a suspended lever that is rotationally displaced about an axis of rotation at right angles to the direction of displacement of the moving part. The lever is connected to the moving part to transmit displacement of the moving part to the lever to cause rotation of the lever about the axis of rotation. The lever is also connected to a first part of the gauge. The sensor comprises a hinge that connects the lever to the substrate. The hinge allows the rotation of the lever about its axis of rotation and is rigid to allow for a lever arm effect. The second part of the gauge is fixed with no degree of freedom to the substrate.
