Claim 5:
6. A sensor unit according to claim 1 wherein, in response to shear force oriented in a direction tangential to the active surface, the first sheet deforms and, as a result of this deformation, at least one of the one or more sensor electrodes moves in the tangential direction relative to the base electrode; and
wherein, for such movement of the at least one of the one or more sensor electrodes, a first capacitance between the at least one of the one or more sensor electrodes and the base electrode either: increases relative to a capacitance between the at least one of the one or more sensor electrodes and the base electrode in an absence of the shear force; or decreases relative to the capacitance between the at least one of the one or more sensor electrodes and the base electrode in the absence of the shear force.
