発明の名称 (英語) PULSE DETECTION DEVICE AND PULSE DETECTION METHOD 新技術説明会
発明の概要(英語) Provided are: a pulse detection device which imposes little restriction on the movement of a subject and has a tolerance for noises; and a pulse detection method. According to the present invention, an oscillation frequency control unit makes a variable-frequency oscillator oscillate at a prescribed oscillation frequency falling within a frequency range that is supposed to be the resonance frequency range of molecules of a prescribed component which constitutes the blood flowing in the human body. Further, the oscillation frequency control unit controls the oscillation frequency on the basis of: a phase difference signal which represents a phase difference between a transmission signal that is transmitted from an antenna to the human body and a reception signal that is received by the antenna; and an amplitude signal which represents the amplitude of the reception signal. A pulse detection unit detects an amplitude-wise change in the amplitude signal as a pulse signal.
