This paper provides the first analysis of accelerometry-derived breathing rate on free-living data including periods of high activity as well as sleep, and test breathing rate estimation on data from a physiological monitor that has not been expressly designed for that purpose.
Adaptive Accelerometry Derived Respiration: Comparison with Respiratory Inductance Plethysmography during Sleep
This work presents a novel method based on a dual tri-axis accelerometer system (Adaptive Accelerometry Derived Respiration, ADR) which was patched on the subject’s chest that adaptively reconstructed thoracic and abdominal respiratory efforts that reflected the good feasibility of the adaptive ADR method for respiration monitoring during sleep.
A Wearable Device for Breathing Frequency Monitoring: A Pilot Study on Patients with Muscular Dystrophy
Preliminary results confirmed that breathing frequency is a valuable breathing parameter to monitor, at the clinic and at home, because it strongly correlates with the main indexes of respiratory function.
Preliminary comparison of respiratory signals using acceleration on neck and humidity in exhaled air
Results show that the accelerometer gently contacting the skin is capable of monitoring the respiration of people undergoing minor movements such as sitting on a chair or standing, and based on acceleration and air humidity using a respiratory sensor.
Breathing Rate Estimation From the Electrocardiogram and Photoplethysmogram: A Review
A review of the literature on BR estimation from the ECG and PPG signals is presented, and the most pressing directions for future research are outlined, including the steps required to use BR algorithms in wearable sensors, remote video monitoring, and clinical practice.
Assessment of Breathing Parameters Using an Inertial Measurement Unit (IMU)-Based System
A new posture-independent processing algorithm for breath-by-breath extraction of breathing temporal parameters from chest-wall inclination change signals measured using inertial measurement units was proposed and successfully reconstructed the respiration-induced movement, and to accurately determine the respiratory rate in an automatic, position-independent manner.
Monitoring cardio-respiratory and posture movements during sleep: What can be achieved by a single motion sensor
The feasibility of using a single accelerometer strapped onto the chest to detect posture and cardio-respiratory parameters during sleep is explored and an efficient movement detector suitable for on-node implementation is developed to distinguish static postures from dynamics movements.
Respiration pattern recognition by wearable mask device.
The aim of this project is to develop signal processing techniques for automatically estimating RR from accelerometry signals measured at the chest, which could allow clinicians to identify deteriorations in health earlier, and respond to them more quickly, potentially improving patient outcomes and reducing healthcare costs.


A Proposal of a Novel Cardiorespiratory Long-term Monitoring Device
A simple, portable, accelerometer-based device suitable for long term-monitoring of the breathing and heart rates, along with postural changes, during sleep and wakefulness and seems to be also suitable for detecting the motor pattern of cough.
Respiratory Rate and Flow Waveform Estimation from Tri-axial Accelerometer Data
A method based on tri-axial accelerometer data from a wireless sensor device, which tracks the axis of rotation and obtains angular rates of breathing motion is demonstrated, which is validated against gyroscope measurements and shows high correlation to flow rate measurements using a nasal cannula.
Performance evaluation of a tri-axial accelerometry-based respiration monitoring for ambient assisted living
The results show that the system can successfully reconstruct the respiration-induced movement, which is necessary to determine the respiratory rate accurately, and performs comparable to PCA.
Estimation of respiratory waveform and heart rate using an accelerometer
The results of experimental evaluation indicate that using a chest-accelerometer can correctly detect the respiratory waveform and heart rate (HR) signal and is suitable for automatic identification some disease, for example arrhythmia or sleep apnea.
Measurement of respiratory rate with high-resolution accelerometer and emfit pressure sensor
This study carried out respiratory rate measurements using a sensor belt with a high-resolution accelerometer (capacitive MEMS) and an EMFit (electret film) pressure sensor, showing that both sensors are feasible for respiratory rate measurement.
Estimation of respiratory waveform using an accelerometer
A method to detect the respiratory waveform from an accelerometer strapped onto the chest is proposed, suitable for automatic identification of some respiratory malfunction, for example during the obstructive apnea.
Handgrip-induced airway dilation in asthmatic patients with bronchoconstriction induced by MCh inhalation.
Sympathetic activation and withdrawal of cholinergic input to the airway smooth muscle reflexly induced by activation of skeletal muscle and carotid sinus receptors may be the primary events accounting for the bronchodilator response induced by handgrip.
Comparison of Respiratory Rate Estimation Based on Tracheal Sounds Versus a Capnograph
The accuracy of the respiratory rate estimated from tracheal sounds on adult subjects was comparable to the accuracy of a commercial capnograph, using as a common reference a pneumotachometer.
