IMU‐Based Respiratory Signal Processing Using Cascade Complementary Filter Method
Journal of Sensors, Volume 2022, Issue 1, 2022., 2022 The purpose of this paper is to propose a cascade complementary filter (CCF) for tracking abdominal or diaphragmatic movement induced by respiratory activity. An inertial sensor (3 DOF accelerometer and 3 DOF gyroscope) is mounted on the upper abdomen, allowing the tilt value of the upper abdomen to be measured.
