Abstract: A force or pressure sensing device comprises one or more magnets resiliently held spaced from one or more magnetic sensors such that pressure on the device displaces the magnets relative to the magnetic field sensors. The device may be incorporated into an insole of a shoe, or integrated into a shoe, or integrated into a seat, cushion, mattress or saddle. The device includes one or more magnetic focussing elements on the opposite side of the magnetic field sensor from the magnets to focus and condition the magnetic field passing through the sensor. The magnetic focussing elements may be permanent magnets or magnetic materials having a high magnetic permeability such as mu-metals. Additional magnetic focussing elements may be placed adjacent to the magnets. Plural magnetic field sensors can be arranged in a symmetrical arrangement in a plane below the one or more magnets so that shear forces applied to the device causes lateral relative displacement of the magnet and magnetic field sensors changing the magnetic field sensed by the magnetic field sensors. The device can also include a motion detector such as an accelerometer which may be integral with the magnetic field sensor.
