CoRSA stands for Cardio-Respiratory monitoring for Sports Activities. We integrated chip-packaged barometers, pulse-oximeters, and inertial measurement units inside head-worn garments to detect the wearer's cardio-respiratory signals.

One major scientific break-through in this study is that we've shown millimeter-sized barometers (BME sensors from Bosch) inside face masks can perform spirometry on par with clinical spirometers through building a physical airflow model and experiment data.
