Multimodal wearable platform for remote monitoring of breathing patterns, cough events and blood oxygen level

ABSTRACT

Wearable technologies are essential for telehealth services and for reducing the load on the healthcare systems. The wearables enable individuals to personalize health monitoring out of hospitals and allow physicians to remotely assess the health status of individuals and track the recovery process. Here, we developed a multimodal wearable device to record breathing patterns and cough events with a low noise, wide dynamic range microelectromechanical accelerometer. In addition, the wearable device included a high-sensitivity pulse oximeter and heart rate to record blood oxygen saturation levels. The device recorded cough vibrations, oxygen saturation level and a respiratory profile that can be used for evaluation of the respiratory system. The device was tested on healthy volunteers and a subject with COVID-19 during quarantine. © COPYRIGHT SPIE. Downloading of the is permitted for personal use only.
