Abstract(in English) | An acoustic sensing that can be used in air has the potential to allow for a fast and accurate characterization of objects. A surrounding environmental sensing technology is widely researched and developed to detect the obstacle for the autonomous movement type robot. Because the person is a very important target when an acoustic sensing is used in the living space, measurements of the vital signs such as the breathing or the position are expected. In this paper, we estimated a time change of reflected wave from a human body to establish the sophisticated acoustic sensing method for the person. The signal used for the measurement is M-sequence signal to improve a SN ratio. Phase difference information was used to detect the very small movement on the surface of human body. Very small movements supposed to be caused by breathing and heart beat was stably observed. Then possibility of noncontact measurement of breath and heart beat using airborne ultrasound was shown. |
