摘要：
PROBLEM TO BE SOLVED: To accurately detect biological information with a fine movement such as a heart rate.SOLUTION: A radio type biological sensor 100 includes an electromagnetic wave irradiation part 10 for irradiating an electromagnetic wave onto a body surface of a living body, a reflection wave reception part 20 for receiving a reflection wave which is generated when the electromagnetic wave irradiated by the electromagnetic wave irradiation part is reflected on the body surface, and acquiring an I signal obtained by multiplying a signal of the irradiated electromagnetic wave by a received reflection signal, and a Q signal obtained by delaying the I signal by a predetermined phase, a differentiation calculation part 90 for differentiating the I signal and the Q signal acquired by the reflection wave reception part, and calculating an I signal differential value and a Q signal differential value, and an angular speed calculation part 40 for calculating angular speeds of the I signal and the Q signal on the basis of the I signal and the Q signal acquired by the reflection wave reception part, and the I signal differential value and the Q signal differential value calculated by the differentiation calculation part on the basis of the I signal and the Q signal.SELECTED DRAWING: Figure 2【課題】 心拍数などの微細な動きを伴う生体情報を正確に検知する。【解決手段】 生体の体表面に電磁波を照射する電磁波照射部１０と、電磁波照射部が照射した電磁波が体表面で反射した反射波を受信し、照射した電磁波の信号と受信した反射信号を乗算したＩ信号とそのＩ信号を所定の位相だけ遅らせたＱ信号を取得する反射波受信部２０と、反射波受信部が取得したＩ信号とＱ信号を微分し、Ｉ信号微分値とＱ信号微分値を算出する微分算出部９０と、反射波受信部が取得したＩ信号とＱ信号、および、Ｉ信号とＱ信号に基づいて微分算出部が算出したＩ信号微分値とＱ信号微分値に基づいて、Ｉ信号とＱ信号の角速度を算出する角速度算出部４０と、を備える電波式生体センサ１００を提供する。【選択図】 図２
