<p>PROBLEM TO BE SOLVED: To make vibration efficiently transmit into a human body to enable to accurately detect the propagated vibration by placing an exciter so as to put the radial artery in between the exciter and the agger on the lower end of wrist radius and a vibration sensor to the heart side than the exciter and bringing those in contact with a human body by an adhesive respectively. SOLUTION: An exciter 1 is fixed on the radial artery 5 in the wrist by self-adhesiveness of a both face adhesive tape 3 and a vibration sensor 2 on the heart side on the same radial artery 5 by a both face adhesive tape 4. The radius lower end agger 7 exists on the lower end of the radius and the radial artery 5 exists right under the skin 6 and the exciter 1 is adhered on a position to put the radial artery 5 in between the exciter and the radius lower end agger 7. The adhesive area of the vibration sensor 2 is divided into an area (b) on the radial artery 5 and areas (a), (c) on both side thereof. Since the areas (a), (c) are in positions far from the radial artery 5 and are fixed without receiving vibration of the radial artery 5, the vibration sensor 2 generates a large flexure in the longitudinal direction and, accordingly, a large voltage is generated in the vibration sensor 2.</p> |
