<p>A force sensor (20) has a pair of backing sheets (23, 25) having confronting surfaces substantially covered with conductive ink to form a pair of conductive layers (29). At least one of the conductive layers is coated with a semiconductive ink. The backing sheets are secured to each other with an interposed layer of non-conductive or insulative material (33), such as adhesive. The layer of non-conductive material is deposited in a pattern and defines at least one sensing area (35). Only when orthogonal force is exerted against the backing sheets at a location corresponding to the sensing area will current flow between the conductive layers.</p> |
