The invention provides a novel capacitive device configured to detect
differences in an applied force over a continuous range of applied force
that includes zero force. The device includes first and second electrodes
that are spaced apart a predetermined distance from each other in a rest
position. A measurable capacitance exists between the first and second
electrodes. Structured elements having a predetermined maximum dimension
are positioned in the device to control the predetermined distance
between the first and second electrodes. An applied force to the device
causes a change in the distance between the first and second electrodes
and a related change in the capacitance that can be measured to determine
information related to the applied force.
