Sweat sensing with chronological assurance
First Claim
Patent Images
1. A sweat sensor device capable of continuous monitoring and chronological assurance comprising:
- one or more sweat sensors adapted to detect a specific solute in sweat and to obtain measurements of said solute in sweat over at least a first time period and a second time period;
a sweat sampling volume between a sampling site on skin and said one or more sweat sensors, said sweat sampling volume at least in part determining a sweat sampling rate; and
electronics adapted to correlate said sweat sampling rate with said measurements from said one or more sensors to provide a chronological assurance of the effective rate at which newly originated sweat reaches said one or more sweat sensors during the first and second time periods.

Abstract
Devices that sense sweat and are capable of providing chronological assurance are described. The device uses at least one sensor to measure sweat or its components and to determine a sweat sampling rate. The chronological assurance is determined, at least in part, using the sweat sampling rate. The sweat sampling rate may be determined, at least in part, using a sweat volume and/or a sweat generation rate, both of which may be measured or predetermined.

27. A method for sensing sweat using a device capable of providing chronological assurance, the method comprising:
-
measuring at least one measurement of sweat using a device comprising one or more sweat sensors; determining a sweat sampling rate; and determining a chronological assurance, wherein the chronological assurance is determined at least in part by the sweat sampling rate. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)

55. A method for sensing sweat from at least two users using devices capable of providing chronological assurance, the method comprising:
-
attaching at least two devices comprising a sensor to at least two users; measuring at least one measurement of sweat using the at least two devices; determining a sweat sampling rate for each of the at least two devices; determining a chronological assurance for each of the at least two devices, wherein the chronological assurance is determined at least in part by the sweat sampling rate; and comparing the chronological assurance for each of the at least two devices.
