Remote pulse wave monitoring system

In this paper we present a novel remote pulse wave monitoring system with hybrid infrastructure network which is based on ZigBee protocol and LAN (local area network) technique. The advantage of this type of network infrastructure is that it can fully make use of the low power consumption of ZigBee protocol in sensor network and the long-distance transmission of LAN technique. Hence, it is a good scheme to be realized in the remote health monitoring. We have designed and fabricated the ZigBee wireless pulse wave detection node that can require the pulse wave data with low power consumption. Several important techniques, such as the ZigBee-LAN exchanging method, the multiresolution analysis for de-noising and removing baseline drift of pulse wave and the calculating method of oxygen saturation and heart rate will be discussed in this paper.
