Abstract
The present invention relates to a touch sensing device, touch screen device comprising a touch sensing device, mobile device, method for sensing a touch and method for manufacturing a touch sensing device allowing various kinds of input operations. The touch sensing device comprises a deformable cover layer; a plurality of capacitive touch sensitive electrode elements arranged in an electrode element layer; and a plurality of pressure sensitive elements each being spatially separated from each other and being coupled to an associated capacitive touch sensitive electrode element of said electrode element layer. One of said plurality of pressure sensitive elements and the associated capacitive touch sensitive electrode element are arranged so that when a current to or from said capacitive touch sensitive electrode element passes through said pressure sensitive element, the voltage across said pressure sensitive element changes in response to a pressure exerted upon said cover layer above said capacitive touch sensitive electrode element.
