    • A wearable device for continuous monitoring of the respiratory rate of a patient, comprising three inertial sensors (10, 11, 12), a first inertial sensor (10) being positioned on the abdomen (13), a second inertial sensor (11) being positioned on the thorax (14), and a third, reference, inertial sensor (12) being positioned on a part of the body (15) not subject to respiratory movements, fixed with respect to the torso. Each inertial sensor (10, 11, 12) comprises an accelerometer, a magnetometer, and a gyroscope. Each inertial sensor (10, 11, 12) comprises a microprocessor (21) connected to said accelerometer, magnetometer, and gyroscope. Said microprocessor (21) is connected to a transmitter (22), and is configured for processing said signals and for supplying to said transmitter (22) a signal represented by a quaternion that describes the orientation of said three inertial sensors with respect to the Earth's reference system. A receiver (30) connected to a control centre (31) is configured for receiving the abdominal quaternion of the first inertial sensor, the thoracic quaternion of the second inertial sensor, and the reference quaternion of the third inertial sensor and is configured for sending them to said control centre (31). Said control centre (31) is configured for processing the quaternions received so that the abdominal quaternion and the thoracic quaternion will be referenced to the reference quaternion. Said control centre (31) comprises a band-pass adaptive filter (55, 56) that filters the signals represented by the abdominal quaternion and by the thoracic quaternion to eliminate the residual components linked to the movements of the patient. Said control centre (31) is configured for calculating the respiratory rate from the signals represented by the filtered abdominal quaternion and the filtered thoracic quaternion.
