Claim 15:
16. A stacked structure composed of a plurality of layers, comprising:
a substrate;
a plurality of conductive patterns printed on the substrate; and
at least one layer of elastic nodules formed between two layers of the plurality of layers, the layer of elastic nodules comprising a sensing area being used for at least one of actuation or sensing;
wherein a hermetically sealed or semi-sealed pouch encases the stacked structure, the hermetically sealed or semi-sealed pouch being formed of a flexible material which has a folded shape or loose shape that allows the volume inside the pouch to change, to accommodate changes in ambient air pressure without hindering the compressive movement of the actuation or sensing of the stacked structure.
