Real-time robust estimation of breathing rate from PPG using commercial-grade smart devices: demo abstract
SenSys '20: Proceedings of the 18th Conference on Embedded Networked Sensor SystemsPages 633–634https://doi.org/10.1145/3384419.3430458In this work, we present a solution for an accurate and real-time monitoring of breathing rate (BR) from photoplethysmogram (PPG) signal on both smartphone and smartwatch. Respiration induces multiple modulations in a PPG signal which are difficult to ...
