Abstract
A touch sensor is presented. The touch sensor comprises a first electrode (21a); a second electrode (21b); a spacing layer (22) disposed between the first and second electrodes to separate the first and second electrodes; a first sealing layer (23a) and a second sealing layer (23b), wherein the first and second electrodes and the spacing layer are disposed between the first and second sealing layers; wherein the first electrode, the second electrode, the spacing layer, the first sealing layer and the second sealing layer are bendable; a capacitive touch circuitry (24) arranged to sense a capacitive coupling between the first and second electrodes and to output a capacitive touch signal as a response to a change in the capacitive coupling; and a charge inducing circuitry (25) connected to the first and second electrodes arranged to independently induce electric charge to the first and second electrodes. A touch sensitive system comprising the touch sensor is also presented.
