1. A touch panel, sequentially comprising:
a first electrode layer;
an elastic dielectric layer; and
a second structure, wherein the second structure comprises:
multiple second circuits in parallel to a second axis;
multiple third circuits in parallel to the first axis;
multiple second electrodes; and
multiple switch circuits,
wherein each of the switch circuits connects one of the second electrodes and one of the second circuits, respectively,
wherein each of the switch circuits is configured to connect or disconnect the one of the second electrodes and the one of the second circuits according to signals transmitted from one of the third circuits,
wherein each of the first electrodes covers at least one of the third circuits, the switch circuits configured by the at least covered one of the third circuits, and the second electrodes corresponding to the switch circuits,
wherein the first electrode layer includes only one first electrode which covers all the second circuits, all the second electrodes, all the third circuits, and all the switch circuits.
