  • Devices with reduced microfluidic volume between sensors and sweat glands
    Patent number: 11253190
    Abstract: A sweat sampling and sensing device for sensing sweat on skin includes an analyte-specific sensor for sensing a first analyte in sweat; a sweat collector placed on or adjacent to skin with a plurality of pores or pathways for entry of sweat from skin into said sweat collector, said sweat collector at least partly defining a sweat volume between said analyte-specific sensor and the skin; and a pressure element capable of holding said sweat collector against the skin with a pressure and reducing the sweat volume between said sweat collector and the skin.
    Type: Grant
    Filed: July 3, 2017
    Date of Patent: February 22, 2022
    Assignees: University of Cincinnati, Eccrine Systems, Inc.
    Inventors: Mark S. Ortiz, Kyle N. Stewart, Robert Roth, Jason Charles Heikenfeld
