To enable highly reliable and stable detection of biological information such as heartbeat and respiration of a subject without imposing a burden on the subject.SOLUTION: A biological information monitor apparatus according to one embodiment includes: an antenna device comprising at least one antenna disposed in close proximity to a subject; a signal generation unit that generates high-frequency signals; a coupling-amount detection unit that detects, using the high-frequency signals, the coupling amount of near-field coupling due to the electric field between the subject and the antenna; and a displacement detection unit that detects a physical displacement of the subject on the basis of change of the coupling amount of the near-field coupling.SELECTED DRAWING: Figure 1 【課題】被検体に負担をかけることなく、被検体の心拍や呼吸などの生体情報を、高い信頼性で安定に検出できるようにする。【解決手段】一実施形態の生体情報モニタ装置は、被検体に近接して配設される少なくとも１つのアンテナからなるアンテナ装置と、高周波信号を生成する信号生成部と、前記高周波信号を用いて、前記被検体と前記アンテナとの間の電界による近傍界結合の結合量を検出する結合量検出部と、前記近傍界結合の結合量の変化に基づき、前記被検体の物理的変位を検出する変位検出部と、を備える。【選択図】 図１
