Testing a wearable sweat sensor to measure insulin levels

This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

Researchers are developing and testing a wearable device that can measure insulin levels through your sweat instead of requiring a blood draw. This device uses electrodes on your skin to gently stimulate sweat production and then measures the insulin in that sweat. The goal is to create a convenient, noninvasive way for people with type 1 diabetes to monitor their insulin levels at home.

Currently, checking insulin levels requires a blood draw at a clinic or lab, which is inconvenient and invasive. This trial is testing whether a wearable sweat sensor could give people with type 1 diabetes a faster, easier, and more accessible way to monitor their insulin at home.

Do you qualify?

You likely qualify if…

you are between 18 and 90 years old
you have been diagnosed with type 1 diabetes (either recently or established)
your BMI is between 18 and 35
you are able to walk, sit, and stand (with or without assistance)
you are willing to wear a continuous glucose monitor during the study
you are willing to stay lying down for up to 9 hours during study visits

You likely don't qualify if…

you are allergic to whey protein, sunflower oil, maltodextrin, or pilocarpine
you have an active serious illness such as heart failure, kidney disease, liver disease, or moderate-to-severe asthma
you are currently taking long-term oral corticosteroids
you have a fever in the last 3 days or active alcohol or drug dependence
you are pregnant or planning elective surgery that requires 2 or more days of hospitalization during the study

What participation looks like

You will visit the Texas A&M research facility for study visits where you'll fast beforehand. During your visit, researchers will measure your body composition, have you complete a 6-minute walk test, and take baseline blood samples through a small catheter in your arm. Then you'll drink a standardized nutritional drink while wearing the wearable sweat sensor on your forearm, which will gently stimulate sweat production and measure insulin levels. Some visits may last up to 9 hours, and you'll need to be willing to wear a continuous glucose monitor throughout the study.
