Abstract

Recently there have been many studies regarding pulse wave velocity (PWV) produced by near-infrared light. However, these studies have used multiple probes with the synchronization problem. This paper proposed a new detecting method to measure PWV on a radial artery with multiple channels in one front-end sensor array. The system was implemented on a MSP430F169 platform and the PWV result was transmitted by RS232 and displayed on the computer screen after being processed. Finally, the PWV result was measured to validate the functionality of the system.
