Abstract: Embodiments disclosed herein are directed to flow assays including at least one electrically-actuated valve configured to control fluid flow. Methods of operating such flow assays are also disclosed.

Abstract: A body fluid sampling device is provided. A mesh (120) may be used to guide blood or fluid to travel directly form the wound to an analyte detecting port on the cartridge (121). Thus the volume of blood or body fluid produced at the wound site irregardless of its droplet geometry can be reliable and substantially completely transported to the analyte detecting member (150) for measurement.

Abstract: Exothermic and/or endothermic chemical reactions in combination with phase change materials can produce output temperature(s) within strict tolerances without requiring expensive and complicated external equipment to generate and maintain an output temperature. Similarly, an exothermic phase change material, which generates heat as a consequence of crystallizing a supercooled liquid, can generate heat at a constant temperature, without requiring expensive and complicated external equipment, as a consequence of the liquid form of the exothermic phase change material being in equilibrium with the solid form of the exothermic phase change material. Numerous biological and chemical processes and/or diagnostic devices require a constant temperature or temperatures for set periods of time.
