Abstract
A sweat sensor includes a first conductor and a second conductor that are parallel with one another. The sweat sensor also includes a channel disposed between the first and second conductors. The channel is configured to receive a sample of sweat. A measure of capacitance between the first and second conductors changes based at least partially upon a volume of the sweat in the channel.
