1. An electronic patch, comprising:

  • a first circuit layer comprising a first flat substrate and a first conductive circuit;

    a second circuit layer comprising a second flat substrate and a second conductive circuit;

    an undulated ribbon that connects the first circuit layer and the second circuit layer, wherein the undulated ribbon includes a third conductive circuit that connects the first conductive circuit and the second conductive circuit, wherein the undulated ribbon is flexible, wherein the undulated ribbon is undulated in a direction perpendicular to the first flat substrate or the second flat substrate, wherein the undulated ribbon is displaced above and below the first flat substrate and the second flat substrate; and

    an elastic layer that encloses the first circuit layer, the second circuit layer, and the undulated ribbons.
