    Abstract: Provided are a chitin-based superabsorbent materials and method of preparation thereof. The superabsorbent material comprises chitin crosslinked by an epoxy crosslinker, and guanidine attached to the crosslinked chitin. The preparation method includes dissolving chitin in an aqueous solvent to form a solution; reacting the dissolved chitin with an epoxy crosslinker and guanidine, or a salt thereof, thereby forming a hydrogel; and drying the hydrogel.

    Abstract: A foldable, waterproof case includes a first wall and a second wall coupled to the first wall. The first and second walls at least partially define a cavity within the case. A lid is coupled to the second wall and is configured to selectively cover the cavity. A hinge is disposed between the first wall and the second wall. The first wall is rotatable relative to the second wall between a first, expanded position of the case and a second, collapsed position of the case. In the first position, the cavity includes a first volume and in the second position, the cavity includes a second volume that is less than the first volume. The hinge provides a waterproof connection between the first and second walls in the first position and in the second position.

    Abstract: The present invention relates to methods for measuring and/or mapping in-plane strain of a surface of a substrate. According to the present invention, a grating is formed on at least a portion of the surface of the substrate. A laser is then used focused onto the grating to determine the strain on the surface by determining the variation of the grating wavelength due to the strain on the surface. The strain information is essentially carried by the grating, in terms of grating wavelength, because it varies according to the volume change of the underlying substrates. By scanning the surface grating with the small laser size, a high resolution strain map of the surface can be produced. The induced strain is related to the grating wavelength variation, which leads to the diffraction angle variation that is captured by the strain sensing measurements.

    Abstract: Systems and methods are described for an edible capacitive power source such as a supercapacitor device. The capacitive power source includes an anode electrode, an anode current collector, a cathode electrode, and a cathode current collector, arranged in layers with a separator layer positioned between the anode electrode and the cathode electrode forming a symmetrical electrical double-layer capacitor. The anode electrode, the anode current collector, the cathode electrode, the cathode current collector, and the separator layer are all constructed of non-toxic, edible materials. The packaging material, the conductive anode tab, and the conductive cathode tab are all also constructed of non-toxic, edible materials forming a completely edible capacitive power source package.

    Abstract: A pneumatic-driven fluidic cartridge and systems and methods for operating the same. The cartridge includes a substrate layer, an actuator layer, and an elastic layer. A fluid channel formed in a surface of the substrate layer includes a first chamber and a second chamber separated by a block section. The actuator layer includes a lever positioned to extend across the block section. The elastic layer is positioned between the substrate layer and the actuator layer. The lever applies a force to the elastic layer restricts fluid flow from the first chamber to the second chamber and is configured to bend outwardly opening a channel between the block section and the elastic layer exceeds the first threshold pressure.
