Abstract: Embodiments herein include testing articles to assess hydration of a test subject. The testing articles can include a carrier portion having a porous medium through which a fluid of the test subject moves. The carrier portion can include a first end and a second end opposite the first end. The testing articles can include a first chemical composition disposed in the porous medium that reacts with chloride ions to produce a first color change. The testing articles can include a wick that is in direct contact with the first end of the carrier portion to allow the transfer of the fluid from the wick to the carrier portion. The testing articles can include a fill indicator element in direct contact with the second end of the carrier portion to allow the transfer of the fluid from the carrier portion to the fill indicator element. Other embodiments are also included herein.

Abstract: Embodiments of the invention include adhesive electrode sets and related methods. In an embodiment, the invention includes an adhesive electrode set. The adhesive electrode set can include a first pad, a first electrode, a first electrical contact, a first conductive lead, a second pad, a second electrode, a second electrical contact, a second conductive lead, a flexible strip, and an adhesive material. The flexible strip can include a fold. The flexible strip can be configured to allow the distance between the first pad and the second pad to increase through flexion of the flexible strip. In an embodiment, the invention includes an analyte receiving test patch. The analyte receiving test patch can include a skin contact layer, a wick, an absorbent layer, a barrier film layer, and an adhesive frame. Other embodiments are also included herein.

Abstract: A water-degradable electrode, its method of preparation and a method or reclaiming valuable metal or metal alloy from such water-degradable electrode after use are provided. The water-degradable electrode contains a water-degradable, electrically nonconductive substrate and a nonphotosensitive, electrically conductive layer containing a metal or metal alloy. The metal- or metal-alloy-containing, nonphotosensitive, electrically conductive layer is disposed on the water-degradable nonconductive substrate. After the electrode has been used, the nonphotosensitive, electrically conductive material can be reclaimed by degrading in water the electrically nonconductive substrate on which the conductive material is disposed.
