When evaluating general health condition on a patient, heart rate is an essential indicator as
it is directly representative of the cardiac system state. Continuous measurement methods of …

In recent decades, wireless healthcare detection has been demonstrated to be an efficient
method for monitoring the health condition of targets; it has involved the detection of motion …

The continuous monitoring of the health status of patients is essential for the effective
monitoring of disease progression and the management of symptoms. Recently, health …

This paper introduces the concept of using acoustic sensing over the radial artery to extract
cardiac parameters for continuous vital sign monitoring. It proposes a novel measurement …

This paper presents a new wearable self-injection-locked sensor with a self-oscillating
active integrated antenna (AIA) and a differentiator-based envelope detector for detecting …

In this article, a novel microwave phased-and perturbation-injection-locked (PPIL) sensor
with a self-oscillating complementary split-ring resonator (SO-CSRR) is proposed for finger …

A radar sensor architecture based on a super-regenerative oscillator (SRO) with very high
sensitivity is presented for vital sign detection and motion sensing. As a proof of concept, the …

People attach greater importance to the physical health of teenagers because adolescence
is a critical period for the healthy development of the human body. With the progress of …

This paper presents a single-frequency continuous-wave (CW) radar that operates
concurrently with two different modes to measure pulse transmit time (PTT) without contact …
