  • Biological-signal detecting device
    Patent number: 6030347
    Abstract: A biological-signal detecting device of a non-wrapper type for accurately detecting a biological signal of a user such as heartbeat number, respiration number or blood pressure, comprises a frame, a spring net fixed to the frame and having an elastic deformation capability to support a weight of the user, and a biological-signal detecting unit. The detecting unit is disposed on a second supporting surface of the spring net opposed to a first supporting surface of the spring net for receiving the weight of the user. The detecting unit determines the biological signal of the user according to a biological vibration which is a cyclic, minute load-variation of the user transmitted through the spring net when the weight of the user is supported by the spring net.
