<p>Provided is a device for detecting motion patterns of a living body, comprising: an impedance detection sensor for having a use area range of the living body as a closed-circuit network; an input node for enabling a motion pattern detection signal of the living body to be inputted from the impedance detection sensor, wherein the motion pattern detection signal of the living body is a voltage signal generated by a temporal variation of a capacitance varying between an impedance detection line and a ground according to a motion of the living body approaching the impedance detection sensor in a state of applying a reference voltage between the impedance detection sensor and the ground; a band pass filter for passing only signals within a range of a frequency band according to the motion patterns of the living body, which correspond a use state of the living body, from among signals inputted from the input node; and a computation and amplification unit amplifying a signal which has passed through the band pass filter and comparing the amplified signal with a set voltage, thereby outputting a voltage signal from which a using state of the living body can be determined.</p> |
