Abstract:
A touch sensing device having conductive nodes is disclosed. The device can include a first structure having one or more conductive electrodes disposed on a surface opposite the structure's touchable surface and a second structure having one or more conductive nodes disposed on a surface. The two surfaces can be placed with the conductive electrodes and conductive nodes facing each other in close proximity so that the electrodes and the nodes can form capacitive elements for sensing a touch on the touchable surface. Separately disposing the conductive nodes from the touchable surface structure can make the touch sensing device thin. An example touch sensing device can be a click wheel.
