Purpose of the study: To develop a wearable sensor that can measure the concentration of chloride ions in sweat. We are trying to develop a sensor that could be used for diagnosis and clinical management of individuals with cystic fibrosis.
Location: Tests will be performed in Croft Hall G10, Homewood campus, in the Searson Lab.
Study procedures: Participants will be asked to exercise on a stationary bike at a fixed level of effort for up to 85 minutes while wearing one or more sensors, along with a conventional wearable fitness sensor to measure physiological parameters such as heart rate.
Eligibility criteria: Healthy individuals (male and female); 18-50 years old who work out at least 2 times per week; Hopkins student or employee.
Compensation. $20 Amazon gift card upon completion of test.
Time commitment: Each test will consist of 85 minutes of exercise, but full test takes 2.5 hours. At least one visit will be required for each participant. Participants completing multiple visits will be restricted to a maximum of one test per day.
