Abstract:
A keyboard device includes a flexible layer, electrical traces on the flexible layer and a lattice substrate to support the flexible layer. The keyboard device further includes a key actuatable to contact the flexible layer and to stretch at least a portion of the flexible layer into an opening in the lattice substrate and a sensor to detect a change of capacitance of the electrical traces in response to actuation of the key by a conductive object.
