Wireless body area networks (WBANs) will take on more diverse forms in terms of their sensor combinations and communication protocols as their presence is extended to a greater number of monitoring scenarios. This paper presents an application layer protocol that solves issues caused by sensor nodes that must compete for high speed, real-time communication with the receiver. Such applications emphasize...
Pulse wave velocity (PWV) has garnered attention as a means to estimate vessel elasticity. This paper presents an approach to measure PWV using two synchronized, wireless pulse oximeters placed on the wrist and fingertip of the same hand. A MATLAB interface acquires and time-aligns these incoming photoplethysmograms (PPGs), and then it calculates PWVs using time differences at three waveform features:...
