Researchers at the University of Texas have announced the development of a wearable device that can measure diabetes-related compounds in tiny amounts of sweat. The monitor detects amounts of cortisol, glucose and interleukin-6 (IL-6), all of which are related to fluctuations in blood glucose levels.
How does the sweat sensor work?
The device requires minimal amounts of sweat for testing — 1 to 3 microliters. Because the device is worn continually, it gives constant readings, unlike devices that test once before being discarded. The developers expect that wearers can use it for about a week before replacing it and intend it to be affordable enough to be used in developing countries. They expect soon to have a cellphone app that will enable wearers to retrieve information that will allow them to analyze how their habits and activities are influencing their diabetes management.
