摘要： A bioinstrumentation device utilizes an optical fiber for measuring biological parameters such as heart rate and breathing rate of a human subject. The device utilizes an optical fiber as a sensing element for sensing minute load variations resulting from the heart beating and breathing of the human subject and therefore indicative of the heart rate and the breathing rate. The device includes a base and a movable member movable relative to the base. The movable member is connected to a support structure for the human body and receives the minute load variations from the living body so as to vibrate in response thereto. Disposed between the base and the movable member is the optical fiber which is capable of resiliently deforming with changing characteristic of its internal reflectivity. A light source is disposed adjacent to the input end of the optical fiber to feed a light through the optical fiber. The light emitted from the optical fiber is received by a light sensor disposed adjacent to the output end of the optical fiber. An analyzing circuit is provided to analyze a variation in the amount of the light received at the light sensor due to the changing internal reflectivity of the optical fiber being deformed so as to determine the biological parameter. A retainer structure is included to keep the optical fiber bent with an initial curvature such that the optical fiber is caused to deform with a varying curvature from the initial curvature in response to minute load variations indicative of the biological parameters to be measured.

摘要： A relax inducing device comprises a biological parameter detecting unit for detecting biological parameter of a user, stimulus loading unit for providing a stimulus to the user, relax-level determining unit for determining a relax level of the user by comparing the biological parameter provided from the biological parameter detecting unit with at least one relax-level threshold value, and a stimulus control unit for controlling an amount of the stimulus according to the relax level to induce the user into a relax state. In this device, since an optimum amount of stimulus is provided to the user on a real-time basis, it is possible to efficiently and smoothly induce the user into the relax state.
