1 is a flow chart illustrating a method for generating health information using body impedance in accordance with one embodiment. Referring to FIG. 1, a method 100 for generating health information using body impedance includes generating an interpolated curve defined by resistance and reactance using a body impedance of a subject measured at a plurality of frequencies (step 110 Calculating 120 a center frequency of the body impedance based on the interpolated curve, and calculating a maximum phase angle (PA), a maximum reactance, and a phase angle for the inspected object using the interpolated curve, (130) at least one of a maximum resistance, a minimum resistance, and a minimum resistance.

In step 110, the health information obtaining apparatus can measure the body impedance of the subject at a plurality of frequencies. More specifically, the measuring unit in the health information obtaining apparatus can measure the body impedance of the subject at at least three frequencies. In the embodiment of FIG. 1, the health information acquisition device measures the body impedance of the subject at three frequencies, but this is merely exemplary and is not intended to limit or limit other embodiments. For example, the idea of the present invention may include a health information acquisition device that generates an interpolated curve using data measured at three or more frequencies and acquires body impedance data through the interpolated curve.

For example, the measurement unit may be configured to measure the first frequency, the second frequency, and the third frequency, which are present at a first frequency in a range of 1 kHz to 10 kHz, a second frequency in a range of 10 kHz to 100 kHz, and a third frequency in a range of 100 kHz to 1000 kHz, The body impedance of the human body can be measured. The above-mentioned frequency ranges are only exemplary descriptions for facilitating understanding of the invention, and should not limit or limit other embodiments. The health information obtaining apparatus can measure the body impedance of the subject at a plurality of frequencies that exist in various ranges according to predetermined conditions.

In addition, at step 110, the health information obtaining device may use the measured body impedance to generate an interpolated curve defined by resistance and reactance. Illustratively, the interpolated curve may represent a two-dimensional curve present in a plane defined by the resistance as the first axis and the reactance as the second axis.

In step 120, the health information obtaining device may calculate the center frequency of the body impedance based on the interpolated curve. Also, in step 130, the health information obtaining apparatus may calculate at least one of the maximum phase angle, the maximum reactance, the maximum resistance, and the minimum resistance for the subject using the interpolated curve and the calculated center frequency. Hereinafter, the process of calculating the center frequency through the interpolated curve of the health information obtaining apparatus through the drawings to be added will be described in more detail.

2A is an exemplary diagram illustrating a process of calculating a center frequency using body impedance measured at a plurality of frequencies according to an embodiment. Referring to FIG. 2A, there are shown three body impedances 211, 212, and 213 measured from a subject at three different frequencies. The X-axis of the graph shown in FIG. 2A represents the resistance (?), And the Y-axis represents the reactance (?).

In the case of the conventional method, since the impedance data of the measured frequency is used as it is, there is a limitation that the dependency of the measurement frequency is applied in the process of determining the health state. However, in the health information acquiring device of this embodiment, even when a frequency suitable for a diseased part to be examined or a target to be examined is not set, a center frequency corresponding to the center frequency is calculated, and a phase angle, a reactance and a resistance value corresponding to the center frequency are extracted And thus can have an effect of judging and monitoring the disease of the subject. In addition, the impedance data at the center frequency is important because the reactance value at the center frequency is greatest. Specifically, the health information obtaining apparatus can use the extracted reactance value as an index for confirming the cell activity indicating the health state of the cell. Further, the health information obtaining apparatus may use the calculated phase angle as an index simultaneously showing the resistance value and the reactance value. According to the above process, the health information obtaining apparatus can generate various health information related to the subject using the calculated impedance data at the center frequency.

In addition, the health information obtaining apparatus can extract not only the center frequency but also the range of the maximum phase angle, the maximum reactance, the center resistance, the maximum resistance, the minimum resistance and the resistance as information on the subject. Hereinafter, a process of extracting information on the subject will be described in detail.

Similarly, the health information obtaining apparatus can calculate the frequency of the second point 260 at which the reactance among the points existing on the interpolated parabola becomes the maximum, as the center frequency of the body impedance.
