Implementation of a wireless pulse oximeter based on wrist band sensor

In order to develop a wrist band pulse oximeter, the detected light intensities and effective transmission depth of reflectance oximetry are investigated by analyzing the light propagation through tissue. A reflectance probe is fabricated based on the analytical results. An oxygen saturation measurement system is also implemented and some preliminary experiments are conducted. The experimental results have confirmed the feasibility of this wrist-band oximeter. Home healthcare can be ensured by transmitting the realtime measurements through wireless technology to the community monitoring system.
