US Patent 11660005 Processing and analyzing biometric data

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.
