摘要：
A method and a device to determine a hydration condition is disclosed. The wearable device may have a top wall, a bottom wall, and a perimeter wall that form an inner cavity. The external surface of the bottom wall may have a projection and an inner surface of the bottom wall may have a channel. A circuit board may have a first portion in the channel, a second portion that extends through a first side wall of the channel to a first recess in the external surface of the bottom wall, and a third portion that extends through a second side wall of the channel to a second recess in the external surface of the bottom wall. A first impedance pad may be on the second portion in the first recess and a second impedance pad may be on the third portion in the second recess.
