INDUSTRIAL APPLICABILITY The present invention is a bio-mounted detection device capable of maintaining good detection sensitivity for movement of a target portion even if the wearing state, skin color of the target portion, water content, skin quality, shape of the target portion, etc. change. I will provide a. The living body-mounted detection device of the present invention includes a light emitting unit, a photoelectric conversion unit, a control unit, and a mounting unit, and the mounting unit mounts the light emitting unit, the photoelectric conversion unit, and the control unit on a living body. The light emitting unit is provided so as to irradiate light toward a target unit that is a target for detecting the movement of a living body, and the photoelectric conversion unit receives light reflected from the target unit and receives light. The control unit is provided so as to generate a current, and the control unit is provided so as to adjust the amount of light emitted to the target unit based on the photocurrent generated by the photoelectric conversion unit, and after adjusting the amount of light. It is characterized in that it is provided so as to detect the movement of the target unit from the change in the photocurrent generated in the photoelectric conversion unit.本発明は、装着状態、対象部の肌の色、水分量、肌質、対象部の形状などが変化したとしても、対象部の動きの検出感度を良好に保つことができる生体装着型検出装置を提供する。本発明の生体装着型検出装置は、発光部と、光電変換部と、制御部と、装着部とを備え、前記装着部は、前記発光部、前記光電変換部、前記制御部を生体に装着させるように設けられ、前記発光部は、生体の動きの検出対象である対象部に向けて光を照射するように設けられ、前記光電変換部は、前記対象部からの反射光を受光し光電流を生じさせるように設けられ、前記制御部は、前記光電変換部で生じた光電流に基づいて前記対象部に照射される光量を調整するように設けられ、かつ、前記光量を調整した後に前記光電変換部で生じた光電流の変化から前記対象部の動きを検出するように設けられることを特徴とする。
