Claim 8:
9. A method of forming a stacked structure composed of
a plurality of layers, the method comprising:
providing a substrate;
printing a plurality of conductive patterns on the substrate;
forming at least one layer of elastic nodules on part of the conductive patterns;
printing or laminating an adhesive layer on but not completely covering the conductive patterns and substrate; and
folding the substrate multiple times to form the stacked structure where at least one layer of elastic nodules is located between two layers of the plurality of layers, wherein for each fold of the substrate, the adhesive layer is folded inward to form the stacked structure by adhering each layer 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 the stacked structure does not comprise electrically conducting through holes or electrically connecting structures.
