摘要

In this paper, we present a novel ultra-wideband (UWB) Terahertz (THz) sensing system for cardiac monitoring and we extract cardiac pulse information from various peripheral body parts by analyzing heartbeat-related skin motions and body motions. Using our system, we demonstrate improved cardiac measurement performance by exploiting unique THz spectral features, narrow focused beam, large signaling bandwidth and superior phase sensitivity, compared to previous results on cardiac measurement. Additionally, we conduct correlation based analysis and show that the Terahertz pulse measure is highly correlated with the contact pulse reference. We compare the estimated heart rates against the reference rates to show accuracy.
