Abstract
In a noncontact vital sign sensing device of the present invention, a gain detector is provided to detect a gain between an oscillation signal and a received signal. Gain detection can cancel out the amplitude noise of an oscillator such that frequency information of vital sign(s) of a subject can be extracted from the gain without null-point issue, and vital sign(s) of the subject located at any position within sensing range can be detected.
