Unlike previous sweat sensors, the new model requires only a trace of moisture to do its job and doesn't require patients to sit still for 30 minutes while it collects sweat. The wearable device, designed in collaboration with researchers at the University of California, Berkeley, contains flexible sensors and microprocessors that stick to the skin and stimulate sweat glands. "Just imagine if you use the wearable sweat sensor with people in clinical drug investigations," he said. More research is needed to see if the wearable sweat sensor would work consistently from one day to the next, since the contents of a person's sweat can change frequently based on diet and other factors. Researchers also hope to learn more about which molecules in sweat can be mapped and may provide the most useful information.
