    Abstract: A flexible differential strain sensor, system, and method includes a deformable substrate having a first axis and a second axis different than the first axis and a first sensing element and a second sensing element. The first and second sensing elements are comprised of conductive gel. The first sensing element is arranged to sense strain in the deformable substrate along the first axis. The second sensing element has a first portion arranged to sense strain in the deformable substrate along the first axis and a second portion arranged to sense strain in the deformable substrate along the second axis. The second sensing element is arranged to cancel at least a portion of the stimulus sensed by the first sensing element in the along the first axis.

    Abstract: A structure may include a first material, a second material joined to the first material at a junction between the first and second materials, and one or more media extending across the junction to form a continuous interconnect between the first and second materials, wherein the first and second materials are heterogeneous. The structure may further include a transition at the junction between the first and second materials. The one or more media may include a functional material which may be electrically conductive. The structure may further include a third material joined to the second material at a second junction between the second and third materials, the media may extend across the second junction to form a continuous interconnect between the first, second, and third materials, and the second and third materials may be heterogeneous.

    Abstract: A sensor may include a bladder, and a deformable conductor disposed on the bladder such that deformation of the bladder causes deformation of the deformable conductor, wherein the bladder is constrained so as to enhance the deformation of the conductor in response to the deformation of the bladder. A method may include applying a stimulus to a bladder having a deformable conductor attached thereto, detecting a change in an electrical characteristic associated with the deformable conductor in response to the stimulus, and selectively constraining the bladder to amplify the change in electrical characteristic in response to the stimulus.
