Title:
BIOLOGICAL INFORMATION DETECTION APPARATUS, VEHICLE AND BED INCLUDING SAME, AND BIOLOGICAL INFORMATION DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/116904
Kind Code:
A1
Abstract:
The present invention realizes a biological information detection apparatus that can obtain highly reliable biological signals from a human body while facilitating price reduction and downsizing of the apparatus by minimizing increase in scale of the apparatus. The biological information detection apparatus comprises: a reflection member (3) that reflects electromagnetic waves; and a radar device (2) that detects biological signals from a human body. The reflection member (3) is disposed between the human body and the radar device (2). The radar device (2) comprises: a transmission unit (2b) for emitting electromagnetic waves toward the human body and the reflection member (3); and a first reception unit (2c1) and a second reception unit (2c2) that receive reflected waves of the electromagnetic waves. The transmission unit (2b) emits electromagnetic waves including a first directional polarization component and a second directional polarization component different from the first directional polarization component. The reflection member (3) reflects the first directional polarization component included in the electromagnetic waves emitted from the transmission unit (2b) and allows transmission therethrough or absorption therein of the second directional polarization component included in the electromagnetic waves emitted from the transmission unit (2b). The first reception unit (2c1) receives at least the first directional polarization component in the reflected waves resulting from reflection by the reflection member (3) and by the human body. The second reception unit (2c2) receives the second directional polarization component in the reflected waves resulting from reflection by the human body.
