Power budgeting is a critical consideration in designing a wearable pulse oximeter for long-term telemedicine application. This paper investigates the potential power saving in a ring-shaped sensor configuration comprising multiple photodetector elements positioned in transmission, transflection and reflection modes. Preliminary in vivo experiments revealed that battery longevity could be extended considerably by employing reflection rather than transflection or transmission mode measurements.
