A 2.4 GHz mutual injection-locked self-injection-locked sensor array provided accurate cardiopulmonary monitoring by cancelling the effects of random body motions of several centimeters.
A mutual injection-locked SIL sensor array can accurately detect vital signs while cancelling the effects of random body movements.
Summary form only given, as follows. This paper presents a self-injection-locked (SIL) sensor array for cancelling the effects of random body movement on the detection of vital signs. The effects of random movements by the subject are cancelled by wireless mutual injection locking (MIL) of the two sensors. In the experiments, a prototype for such a array with a spacing of 2 m was implemented at 2.4 GHz, providing accurate and reliable cardiopulmonary monitoring of a subject who exhibited random body motions of several centimeters.
Wang et al. (Wed,) conducted a other in Vital sign detection. Mutual injection-locked self-injection-locked (SIL) sensor array was evaluated on Accurate and reliable cardiopulmonary monitoring with random body movement cancellation. A 2.4 GHz mutual injection-locked self-injection-locked sensor array provided accurate cardiopulmonary monitoring by cancelling the effects of random body motions of several centimeters.
