SWEAT COLLECTION DEVICES FOR GLUCOSE MEASUREMENT
First Claim
1. A device comprising:
- a channel layer configured to direct sweat that has come to the skin surface to an opening;
a container layer in fluid communication with the opening and defining at least a portion of a container configured to contain a volume of less than about one microliter of the sweat; and
a vent layer comprising a vent adjacent to the container.

Abstract
Devices, methods, and kits for collecting sweat that has come to the surface of the skin are provided. The sweat may be collected for measuring sweat glucose levels. Because sweat glucose levels correlate to blood glucose levels, the provided devices, methods, and kits may be used by diabetic patients to non-invasively monitor blood glucose levels. Sweat collection devices may be attachable to the surface of the skin and may collect about one microliter or less of sweat. Because only a small, fixed volume of sweat may be collected, the sweat glucose level may be measured in a matter of minutes. Further, as a fixed volume of sweat is tested, inaccuracies due to estimates of the sweat volume being tested are less likely to cause an inaccurate glucose measurement.
