A pressure sensing pad includes a first substrate, a second substrate, a first electrode layer, a second electrode layer, and a spacer layer. The second substrate is disposed opposite to the first substrate. The first electrode layer is disposed on one side of the first substrate facing the second substrate, and the first electrode layer includes at least one first electrode pattern. The second electrode layer is disposed on one side of the second substrate facing the first substrate, and the second electrode layer includes at least one second electrode pattern. The spacer layer is disposed between the first substrate and the second substrate. The spacer layer includes a plurality of openings, so that when a user presses the first substrate, the first electrode pattern contacts the second electrode pattern through the opening. |
