Sweat, like blood, can tell us a lot about a person's health. And conveniently, it's a lot less invasive to collect. This is the premise behind the wearable sweat sensors developed by Wei Gao, assistant professor of medical engineering, Heritage Medical Research Institute Investigator, and Ronald and JoAnne Willens Scholar.. Over the past five years, Gao has steadily added features to his wearables, making them capable of reading out levels of salts, sugars, uric acid , amino acids, and vitamins as well as more complex molecules like C-reactive protein that can provide timely assessment of certain health risks.
