1. A sensing device comprising:
a resonant member that is movable in a first mode and a second mode; and
an electrode,
wherein the resonant member has a capacitive surface portion that faces and is capacitively coupled to a capacitive surface portion of the electrode,
wherein displacement for each point along the capacitive surface portion of the resonant member in the first mode is substantially tangent to the point.
