Abstract
The present disclosure generally relates to wearable devices and methods for measuring a photoplethysmographic (PPG) signal. The wearable devices and methods described herein are capable of obtaining PPG signals by employing a PPG sensor array configured to receive light at angles associated with a high perfusion index. Viewing components may be coupled to the PPG sensor array to effect transmission of light at these preferential angles.
