PROBLEM TO BE SOLVED: To provide a biological information detection apparatus and method capable of detecting a biological state regarding a living body by detecting a change in an effective dielectric constant of the living body from a propagation delay time between a transmitted pulse signal and a received pulse signal.SOLUTION: The biological information detection apparatus according to the present invention includes: detection means 10 formed by laying an electric conductor 11 in a sheet-like shape a transmission part 22 for transmitting a pulse signal to the electric conductor 11 a reception part 23 for receiving a pulse signal propagating through the detection means 10 a measurement part 24 that measures a propagation delay time by comparing the pulse signal transmitted from the transmission part 22 with the pulse signal received by the reception part 23 and a biological state detection part 25 that detects a change in an effective dielectric constant of the living body from the propagation delay time measured by the measurement part 24. The biological information detection apparatus is characterized in that the detection means 10 is used in proximity to the living body.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】送信したパルス信号と受信したパルス信号との伝播遅延時間から生体の実効誘電率の変化を検出することで、生体に関して生体状態を検出できる生体情報検出装置および生体情報検出方法を提供すること。【解決手段】本発明の生体情報検出装置は、導体11をシート状に敷設した検出手段10と、導体11にパルス信号を送信する送信部22と、検出手段10を伝播したパルス信号を受信する受信部23と、送信部22から送信したパルス信号と受信部23で受信したパルス信号とを比較して伝播遅延時間を計測する計測部24と、計測部24で計測した伝播遅延時間から生体の実効誘電率の変化を検出する生体状態検出部25とを備え、検出手段10を生体に近接させて用いることを特徴とする。【選択図】 図1
