Multiple Light Paths Architecture and Obscuration Methods for Signal and Perfusion Index Optimization

A photoplethysmographic (PPG) device is disclosed. The PPG device can include one or more light emitters and one or more light sensors to generate the multiple light paths for measuring a PPG signal and perfusion indices of a user. The multiple light paths between each pair of light emitters and lig...
