Abstract
The systems and methods described herein provide a wearable sweat sensing device. The device includes a sweat patch component including a sweat biochemical sensor patch having a substrate defining a hole, at least one biochemical sensor, and a capture wick including a tip that extends through the hole, the capture wick configured to channel sweat across the at least one biochemical sensor. The sweat patch component further includes a wick downstream from the capture wick and separated from the capture wick by a gap, and electronic circuitry disposed against at least one face of the wick, wherein an electronic response of the electronic circuitry changes as sweat flows through the wick. The wearable sweat sensing device further includes an electronics module component configured to facilitate assessing hydration of a wearer based on signals from the at least one biochemical sensor and the electronic circuitry.
