Claim 0:
1. A sweat sensing device capable of directly measuring sweat flow rate comprising:
at least one flow rate sensor for measuring a sweat flow rate;
at least one analyte sensor for measuring a characteristic of an analyte in sweat; and
a microfluidic component comprising a fluid pathway for conveying at least one sweat sample into fluid communication with the at least one flow rate sensor, the at least one analyte sensor, or both the at least one flow rate sensor and the at least one analyte sensor, wherein the pathway has a first portion for collecting a sample and a second portion adjacent to the at least one flow rate sensor and the at least one analyte sensor, wherein the second portion has a volume-reduced pathway relative to the first portion;
wherein the second portion of the fluid pathway comprises a first valve and a second valve, wherein the first valve is positioned in a portion of the fluid pathway preceding the flow rate sensor, and wherein the second valve is positioned in a portion of the fluid pathway following the flow rate sensor.
