We develop new human measurement techniques with the establishment of innovative systems theory by combining system theory, electromagnetic theory, and medical engineering. Prior knowledge on the human body shape and vital signs is effectively used for optimizing the whole human measurement system, which is expected to break through the existing resolution limit of conventional sensing techniques.
Wireless sensing allows us to detect small displacements of the human skin surface that are caused by the heartbeat and respiration, which realizes non-contact monitoring of heart rate and respiration rate in addition to other person-specific parameters.
We aim to develop wireless human imaging systems with an extreme accuracy exploiting a priori knowledge on human shapes. One of the applications of this technology is the detection of concealed weapons and objects, which is frequently used in passenger screening systems at security checkpoints of airports.
