Wei Gao, Assistant Professor of Medical Engineering, has produced a wireless sweat sensor that can accurately detect levels of cortisol, a natural compound that is commonly thought of as the body's stress hormone. This could allow for more widespread and easier monitoring of stress, anxiety, post-traumatic stress disorder, and depression. "We aim to develop a wearable system that can collect multimodal data, including both vital sign and molecular biomarker information, to obtain the accurate classification for deep space stress and anxiety," Gao says.
