May extend wearable SpO2 battery life via forehead reflectance designs; leaves open clinical validation.
Using a wide annularly shaped photodetector ring on the forehead can optimize power consumption for wearable reflectance pulse oximeters.
Mendelson et al. (2004) studied Pulse oximetry monitoring. Wide annularly shaped photodetector ring and forehead measurement site was evaluated on Power saving and battery longevity. Employing a wide annularly shaped photodetector ring and performing SpO2 measurements from the forehead region considerably extended battery longevity in wearable reflectance pulse oximeters.
