Abstract: A composition for application to a substrate to form a film or deposit for quantifying a fluid, or one or more analytes within a fluid, is disclosed. The composition includes a carrier configured as a transport medium for application of the composition to a substrate and at least one salt of chloranilic acid. The carrier can include at least one compound soluble within a bodily fluid and configured to at least partially solidify upon application of the composition on the substrate. The carrier can optionally include a liquid medium as a bulk transport medium for application of the composition. In some aspects, the liquid medium can be water, the at least one compound can be one or more water-soluble polymers, and the salt of chloranilic acid can be silver chloranilate.

Abstract: The present invention describes multilayered adhesive structures that can be used as adhesives to mount wearable devices onto the skin. The multilayered adhesive structures can comprise a buffer layer sandwiched between two adhesive layers, a first adhesive layer adhering the multilayered adhesive structure to the wearable device and a second adhesive layer adhering the buffer layer to the skin. The buffer layer separates or isolates the wearable device from the skin. By mechanically buffering the wearable device from the skin, the multilayered adhesive structures permit the devices to be skin-mounted for an extended period of time (e.g., a few hours or days) without causing moisture-associated skin injuries such as erythema, maceration, and irritation or inflammation.

Abstract: The present invention describes breathable multilayered adhesive structures that can be used as adhesives to mount devices onto the skin. The breathable multilayered adhesive structures can comprise moisture-wicking layers adhered to the skin by a porous adhesion layer. The pores allow moisture released from the skin to be transferred away through the moisture-wicking layer. The adhesive structures permit the devices to be skin-mounted for an extended period of time (e.g., a few hours or days) without causing moisture-associated skin injuries such as erythema, maceration, and irritation or inflammation.
