Capacitive sensor for sensing tactile and proximity, and a sensing system using the same
A capacitive sensor includes an upper electrode layer having a plurality of electrodes disposed in line with each other, a lower electrode layer having a plurality of electrodes disposed in line with each other, an insulating layer disposed between the upper electrode layer and the lower electrode layer, and a layer of bumps made of insulating material formed above the area where the electrodes of the upper electrode layer and the electrodes of the lower electrode later are crossed. The sensor detects the proximity of approaching objects by the capacitance change between the electrodes disposed in the upper electrode layer, and detects the contact of any objects by the capacitance change between the electrodes of the upper electrode layer and the electrodes of the lower electrode layer.
