Abstract
Disclosed are various embodiments for a flexible hydration sensor that can be implemented in a wearable device. A hydration monitoring device can include at least one flexible electrode comprising a plurality of silver nanowires embedded within a polydimethylsiloxane (PDMS) substrate. Processing circuitry can be configured to measure a hydration level of an individual wearing the hydration monitoring device based at least in part on a measurement of a skin impedance of the individual. In some embodiments, the hydration monitoring device can also generate a hydration metric based on the level of hydration and display the hydration metric.
