Claim 0:
1. A touch sensor, comprising:
a base layer;
a plurality of first touch electrodes arranged on the base layer in a second direction crossing a first direction;
a plurality of second touch electrodes arranged on the base layer in the first direction;
at least one strain gauge arranged on the base layer and disposed between the plurality of first touch electrodes, the at least one strain gauge being configured to sense a pressure, wherein no other strain gauge besides the at least one strain gauge is disposed on the base layer;
a first connection electrode connecting the plurality of first touch electrodes in the second direction; and
a second connection electrode connecting the plurality of second touch electrodes in the first direction,
wherein the plurality of first touch electrodes and the strain gauge are arranged on a same layer, and wherein each of the plurality of first touch electrodes and each of the plurality of second touch electrodes are electrically insulated from the strain gauge and in which no other strain gauge is electrically connected to any of the plurality of first touch electrodes and any of the second touch electrodes,
wherein the plurality of first touch electrodes are arranged in a plurality of rows and the plurality of second touch electrodes are arranged in a plurality of columns on a top surface of the base layer, in which no strain gauge disposed on the base layer is electrically connected to any of the first touch electrodes and any of the second touch electrodes,
wherein the first connection electrode is disposed between the base layer and the plurality of first touch electrodes,
wherein the second connection electrode and the first connection electrode are disposed on different layers from each other, and the second connection electrode overlaps the first connection electrode in the thickness direction, and
wherein the first connection electrode traverses one of the at least one strain gauge and overlaps the one of the at least one strain gauge at a plurality of points that are spaced apart from one another.
