Abstract
Described herein are apparatuses and methods for measuring a hydration condition with a wearable device. The wearable device may include a housing, a flume integrated into the housing, and a sensor array. The housing may include a perimeter wall disposed around a perimeter of the housing between a top wall and a bottom wall, where the top wall, bottom wall, and perimeter wall form an inner cavity. The flume may be disposed in the inner cavity, where a first end of the flume is disposed at the bottom wall and a second end of the flume is disposed at the top wall. The sensor array may include a first vapor pressure sensor located within the flume at a first location and a second vapor pressure sensor located within the flume at a second location.
