  • Publication number: 20220412914
    Abstract: Biological chemicals, potentially found in blood are measured by collecting sweat and determining the concentration or meaning of the selected chemical in sweat. The sweat can be collected using a time based, interval collector and analyzed using an external device. It can also be collected on a one time basis, using a flexible, chemical capacitor, or on a continuous basis using a chemical, field effect transducer.
    Type: Application

  • Publication number: 20170172484
    Abstract: A wearable sweat sensor device (1) may include a plurality of sensors (150, 160, 170, 180) capable of measuring a plurality of ion-selective biomarker potentials and a mechanism that analyzes a combination of measurements as a proxy for one or more physiological conditions such as muscle activity, exertion, or tissue damage. A device may include a sensor capable of taking at least one skin impedance measurement along with a plurality of sensors (150, 160, 170, 180) and a mechanism that analyzes a combination of measurements as a proxy for one or more physiological conditions, such as hydration or sweat rate. Because several of said sensors (150, 160, 170, 180) may not be stable when stored if fully exposed to air, the device (1) may include a temporary seal (400) for said sensors (150, 160, 170, 180) that is removable prior to placement and use of said sensors (150, 160, 170, 180).

  • Publication number: 20170016892
    Abstract: A biomarker sensor using short peptide recognition elements. The biomarker sensor includes a substrate and a metallic layer on a surface of that substrate that is localized surface plasmon resonance reactive. A receptor layer on the surface of the metallic layer (the surface opposing the substrate) is configured to selectively bind a biomarker and has a thickness less than about 15 nm.
