Brief Description
This invention is a printed, flexible, two-channel reflectance oximeter able to collect PPG signals using red and near- infrared (NIR) (or green) organic light-emitting diodes (OLEDs) and organic photodiodes (OPDs). Inverse-variance weighting and template matching algorithms are used to improve the detection of heart rate from the multi-channel PPG signals.
Suggested uses
This invention is useful for and in wearable smart watches and wristbands.
Advantages
This varied reflectance oximeter sensor has varying device geometry, light emitter and detector spacing. In certain embodiments, an optical barrier between the emitter and the detector is provided to maximize sensor performance.
