Abstract: A pressure sensor comprises: a first electrode layer; a second electrode layer; and an intermediate layer disposed between the first electrode layer and the second electrode layer, wherein the intermediate layer changes in resistance, depending on a change in at least one of a thickness or a volume thereof. In addition, the intermediate layer comprises: a foam having porous regions dispersed in a non-porous region thereof; and a conductive material being dispersed in the foam and being more conductive than the foam.
