Abstract
Low power management without compromising signal quality is a key requirement in the optimal design of a wearable pulse oximeter. This paper investigates the advantage gained by using a photodetector with a larger active area. Preliminary in vivo experiments have demonstrated that by increasing the area of the photodetector it is possible to reduce the overall power requirement of a wireless sensor intended for telemedicine applications.
