Abstract
A force-touch sensor with multilayered electrodes includes an upper substrate, a first electrode layer arranged on one face of the upper substrate and having a plurality of first sensing electrodes, a second electrode layer arranged opposite to the first electrode layer and having a plurality of second sensing electrodes, each second sensing electrode being electrically connected with one corresponding first sensing electrode to constitute a touch-sensing electrode, a plurality of touching sensing traces, each electrically connected with one touch-sensing electrode and electrically isolated with other touch-sensing electrodes, a resilient dielectric layer arranged on one face of the second electrode layer and opposite to the upper substrate, and a third electrode layer arranged on the resilient dielectric layer and having at least one force-sensing electrode. The force-touch sensor with has enhanced performance due to the multilayered electrodes structure.
