Abstract: A pulse wave detecting device includes a sensor section and a control unit. The sensor section is rotatable about a first axis and is rotatable about a second axis. The control unit determines a rotation angle about the second axis based on DC components of a plurality of a pressure detecting elements included in at least one of element rows. Then, the sensor section is pressed against the body surface in a state that the sensor section is controlled in the optimal roll angle, the pulse wave is detected based on pressure signals detected from the pressure detecting elements and the vital information is calculated based on the detected pulse wave.

Abstract: A pulse wave detection apparatus has a sensor chip that includes a substrate that has a shape of extending so as to be elongated in an X direction, and that is arranged so as to intersect an artery. A pressure sensor array is formed on the substrate and is made up of pressure sensor elements that are arranged side-by-side in the X direction. An electrode terminal array for transmitting output from the pressure sensor elements to the outside of the sensor chip is formed in a region that opposes an end portion of the pressure sensor array on the substrate. Regions that correspond to two sides of the pressure sensor array on the substrate are planar surfaces on which electrode terminals are not located.

Abstract: A measurement device includes a pulse wave signal acquisition unit, a pulse wave velocity calculator, a transfer function calculator, a phase diagram classifier, and an aneurysm determinator. The pulse wave signal acquisition unit acquires time-series pulse wave signals of each of an upper arm and an ankle of the subject. The pulse wave velocity calculator obtains a brachial-ankle pulse wave velocity based on the pulse wave signal of the upper arm and the pulse wave signal of the ankle. The transfer function calculator calculates a transfer function from the pulse wave signal of the upper arm and the pulse wave signal of the ankle. The phase diagram classifier classifies the phase diagram of each subject into any one of four groups. The aneurysm determinator determines presence or absence of the abdominal aortic aneurysm by a criterion set according to each group.

Abstract: A pulse wave detection method includes: increasing a pressing force of a pressing member for pressing a strain sensor fixed thereto against a body surface, the flexible strain sensor having a plurality of strain detection elements arranged on a substrate; determining a deformation stop timing at which deformation of a detection face of the strain sensor has been stopped based on the strain detection signal detected by each of the plurality of strain detection elements in a pressure raising process in which the pressing force is increased; setting a level of the strain detection signal detected at the deformation stop timing as a reference level; calibrating the first strain detection signal detected after the deformation stop timing based on the reference level; and generating a pressure signal from the calibrated first strain detection signal.
