Abstract
A capacitive sensor that responds by measuring a change in capacitance induced by application of force includes a first capacitive plate having an electrically conductive touch cell, a second capacitive plate spaced from the first capacitive plate and having an electrically conductive area generally parallel with and overlapped with the touch cell, an incompressible spacer between the capacitive plates and having an aperture defining an air gap adjacent the touch cell, and a flexible dielectric touch plate overlying a flexible one of the first and second capacitive plates. The flexibility of the touch plate and adjacent capacitive plate allows finger pressure on the touch plate at the touch cell to change the dimension of the air gap and capacitance between the touch cell and a conductive region of the second capacitive plate.
