Supports low-power remote vital signs detection; leaves open clinical validation before adoption.
A novel Ka-band transceiver demonstrates high accuracy for remote detection of vital signs using very low transmitted power, offering potential for non-contact patient monitoring.
Xiao et al. (2006) studied Detection of human heartbeat and respiration signals. Ka-band transceiver using low-power double-sideband transmission was evaluated on Detection accuracy at a distance of 2.0 m. A Ka-band radar sensor system achieved better than 80% detection accuracy for human heartbeat and respiration at a distance of 2.0 m with a transmitted power of 12.5 µW.
