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).
