1. A stretchable flexible pressure sensor comprising:

  • a. an elastic substrate comprising a material that enables the elastic substrate to be stretched in one or more directions, wherein the elastic substrate comprises a first surface and an opposing second surface and a gap extending through the elastic substrate;

    b. a first stretchable conductive interconnect coupled to the first surface of the elastic substrate, wherein at least a portion of the first stretchable conductive interconnect has a meandering shape aligned with the gap in the elastic substrate; and

    c. a second stretchable conductive interconnect coupled to the second surface of the elastic substrate, wherein at least a portion of the second stretchable conductive interconnect has the meandering shape and is aligned with the gap in the elastic substrate, and the meandering shapes of each of the first stretchable conductive interconnect and the second stretchable conductive interconnect are aligned to form a pressure sensor, wherein a shape of the gap is the meandering shape, and the first stretchable conductive interconnect, the second stretchable conductive interconnect, and the gap are co-aligned.
