Abstract
A capacitive touch keyboard includes a sensor layer, ground plane, a flexible sensed body, and a sensing circuit. The sensor layer includes a substrate and a key sensing cell which disposed on the substrate spaced apart from the ground plane. The flexible sensed body includes a sensed portion and a connected portion connected with the ground plane where the sensed portion obliquely extends to above the key sensing cell such that the flexible sensed body and the key sensing cell jointly form a capacitor structure. The sensing circuit is electrically connected to the sensing cell for probing a capacitance change. Therefore, features of more simplified structure design, tactile feel, and improved durability are provided in a capacitive keyboard.
