ABSTRACT:
A force sensor and method for making same. A pair of backing sheets having confronting surfaces are substantially covered with conductive ink to form a pair of conductive layers. 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, such as adhesive. The layer of non-conductive material is deposited in a pattern and defines at least one sensing area. 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.
