Medical monitoring has improved over the last four decades to include increasingly less
invasive techniques. In particular, Doppler radar methods are emerging as a means for …

During the pandemic of coronavirus disease-2019 (COVID-19), medical practitioners need
non-contact devices to reduce the risk of spreading the virus. People with COVID-19 usually …

In light of the continuously and rapidly growing senior and geriatric population, the research
of new technologies enabling long-term remote patient monitoring plays an important role …

A 110-mW 39-GHz Doppler radar front end in 65-nm CMOS for displacement and vibration
sensing is proposed. Conventional Doppler radar suffers from detection nulls, at which the …

A highly accurate 3-D indoor passive localization and identification system is presented in
this article. The system can monitor various commercial Wi-Fi devices through the proposed …

WiFi sensing, an emerging sensing technology, has been widely used in vital sign
monitoring. However, most respiration monitoring studies have focused on single-person …

During the global epidemic, non-contact methods for monitoring the vital signs of several
people have become particularly important. Advanced signal processing techniques have …

The distributed-multiple-input multiple-output (MIMO) continuous-wave (CW) radar with low-
intermediate frequency (low-IF) receiver that is proposed in this work uses uniform linear …

Compared with a conventional Doppler radar in which target displacement results in phase
modulation, target displacement in a self-injection-locked oscillator (SILO)-based radar …

Radio frequency (RF) signals are widely used in respiratory detection due to their non-
contact, remote sensing advantages. In order to satisfy multiperson monitoring, the existing …
