1. A sensor patch comprising:
a perspiration volume sensing channel including at least a first colorimetric material that changes color in response to exposure to perspiration;
a perspiration component sensing chamber including at least a second colorimetric material that changes color in response to exposure to a biochemical component in the perspiration;
a near field communication circuit and a near field communication antenna; and
a plurality of the perspiration component sensing chamber, each perspiration component sensing chamber including a chamber inlet port in fluid communication with the perspiration component sensing chamber to allow the perspiration to enter into the perspiration component sensing chamber,
wherein two or more of the plurality of chamber inlet ports have different diameters to measure different collection rates of the perspiration.
