Abstract: A conformal patch device can be provided to a patient. The patch device can include sensors configured to be positioned over a chest of a patient. The sensors can include PPG sensors, ECG sensors, and SCG sensors. The conformal patch device can adhere to a single continuous area of the chest. Some sensors may attached to a viscoelastic substrate to achieve mechanical isolation from other patch components. The conformal patch device can capture measurements from the sensor doing a time window sufficient enough to detect disordered breathing. The system can determine disordered breathing and related cardiorespiratory parameters during the time window for the patient using the sensor measurements.

Abstract: The present disclosure relates to a cardiorespiratory analysis system that includes, in at least one embodiment, a conformal patch with a compressible viscoelastic interface and an array of sensors, including, but not limited to a photoplethysmography (PPG) sensor, a 3-axis accelerometer, and an electrocardiogram (ECG) sensor. In at least one embodiment, the system includes a microcontroller wired to the array of sensors. According to at least one embodiment, the system uses computing techniques to derive features from the array of sensors and determines one or cardiorespiratory characteristics of a patient based on the derived features.
