A monitoring system of pulse wave transit time based on wireless sensor networks
Abstract：With the occurrence of wireless sensor networks,low-load monitoring has a revolutionary change.Using wireless sensor networks,the whole monitoring system is composed of wireless electrocardiogram(ECG)sensors and wireless pulse wave sensors.Pulse wave signals from the temporal artery and ECG signals from the body synchronously were measured.Pulse Wave Transit Time was calculated.Both the wireless ECG sensor and the wireless pulse wave sensor were small sized and powered by button battery;the precision of time synchronization among sensors was less than 1 ms.The calculated Pulse Wave Transit Time changed slowly with deep breathing.The system iS able to work smoothly for continuous monitoting of Pulse Wave Transit Time in working conditions.
