5 is a detailed block diagram of a partial body fat measurement unit according to an embodiment of the present invention shown in FIG. 2 .

Referring to FIG. 5 , the partial body fat measurement unit 220 may include a body resistance measurement module 502 and a subcutaneous fat measurement module 504 . The body resistance measurement module 502 and the subcutaneous fat measurement module 504 may be connected to predetermined measurement electrodes A, B, C, and D as shown in FIG. 4B . The predetermined measurement electrodes A, B, C, and D may be switched through a predetermined switching unit to be used jointly when measuring body resistance or subcutaneous fat, and may be connected to a corresponding measurement module. In FIG. 4B , it is illustrated that predetermined measurement electrodes A, B, C, and D are jointly used for the body resistance measurement module 502 and the subcutaneous fat measurement module 504 , but the present invention is not limited thereto. A predetermined measuring electrode may be connected to each of the 502 and the subcutaneous fat measurement module 504 .

The body resistance measurement module 502 may detect a magnitude of body resistance according to the amount of body fat of a body measurement part to be measured by the examinee. The body resistance measurement module 502 may measure two types of body resistance according to a measurement method. For example, the body resistance measuring module 502 applies an alternating current to pass through the body measuring part through two electrodes (eg, A and B) (see FIG. 4B ) in contact with the body measuring part, and the Through the other two electrodes (eg, C, D) (refer to FIG. 4B ) in contact with the body measurement part, the AC voltage when the AC current passes through the body measurement part may be measured. The body resistance measuring module 502 may detect an impedance value [Ω] of the corresponding body measuring part calculated using the AC current applied to the body measuring part and the AC voltage measured from the body measuring part. The alternating current applied to the body measurement part may have a range of, for example, about 1 KHz to 1 GHz. The impedance value may have a different impedance standard range according to a body measurement part. In addition, the body resistance measurement module 502 may detect an impedance value using a phase delay between the AC current applied to the body measurement region and the detected AC voltage. Assuming that the minimum electrode configuration (at least four) for impedance measurement is one measurement channel, the body resistance measurement module 502 according to an embodiment of the present invention may have at least one impedance measurement channel, The impedance of at least one body measurement part may be measured at a time by using at least one impedance measurement channel. When the electronic device 200 has the at least one impedance measurement channel, the electronic device 200 may further include at least one position sensor unit corresponding to each measurement channel. The controller 280 may distinguish and determine a body measurement part according to the impedance value detected by the body resistance measurement module 502 , and may analyze a partial body composition of the corresponding body measurement part using the impedance value.

The body resistance measuring module 502 applies a direct current to pass through the body measuring part through two electrodes (eg, A, B) (see FIG. 4B ) in contact with the body measuring part, and applying the direct current to the body measuring part. Through the other two electrodes (eg, C and D) in contact (see FIG. 4B ), a DC voltage when the DC current passes through the body measurement part may be measured. The body resistance measuring module 502 may detect the skin conductivity value [Ω] of the body measuring part calculated using the DC current applied to the body measuring part and the DC voltage measured from the body measuring part. That is, the skin conductivity is a measurement value in which a temporary change in electrical resistance is sensed by a weak electrical signal (DC current) applied to the body measurement site, and has a different skin conductivity standard range depending on the contact area, that is, the body measurement area. can The control unit 280 can distinguish and determine the contact area of the measuring electrodes A, B, C, and D (refer to FIG. 4B ), that is, the body measuring area, according to the skin conductivity value detected from the body resistance measuring module 502 . have.

The subcutaneous fat measurement module 504 may detect a thickness of subcutaneous fat according to the amount of body fat of a body measurement part to be measured by the examinee. The subcutaneous fat measurement module 504 may detect the thickness of the subcutaneous fat of the corresponding body measurement area using various measurement methods (eg, measurement using an RF signal, ultrasound, or a light source). For example, in the case of subcutaneous fat measurement using an RF signal, the subcutaneous fat measurement module 504 transmits an RF signal having a frequency of about 0.1 to 200 GHz through measuring electrodes (eg, A and B) (see FIG. 4B ). The thickness of the subcutaneous fat of the body measurement site by measuring the signal that is applied to the body measurement site and the RF signal absorbed by the body fat of the body measurement site is reflected and returned through the measuring electrodes (eg, C, D) (refer to FIG. 4B ) can be detected. The detected subcutaneous fat thickness may have a different subcutaneous fat thickness standard range depending on a body measurement site.

Since the impedance value, the skin conductivity value, and the subcutaneous fat thickness have different standard ranges for each body part, the controller 280 detects the impedance value, the skin conductivity value, and the subcutaneous fat thickness from the partial body fat measurement unit 220 . At least one candidate body measurement part corresponding to the detected body fat measurement information may be determined from among a plurality of preset body parts by using body fat measurement information including at least one. An example of the body fat-based standard range for each body part is tabulated in [Table 1] below.

torso (TR) right arm (RA) Left arm (LA) right leg (RL) Left leg (LL) Impedance [Ω] 10 to 50 300-500 300-500 200-300 200-300 Skin conductivity [Ω] 1-9M 50-70M 50-70M 65~90M 65~90M Subcutaneous fat thickness [mm] 10-30 4-15 4-15 5-17 5-17

As shown in [Table 1], a number of body fat-based standard ranges (e.g., impedance per body part, skin conductivity) by body part (e.g., trunk (TR), arms (RA, LA), and legs (RL, LL)) and thickness of subcutaneous fat) may vary depending on the age, sex, and height of the subject. The body fat-based standard ranges for a plurality of body parts according to age, gender, and height are stored in advance in the storage unit 240 or downloaded from the outside (eg, server 106) through the communication unit 270 and stored in the storage unit 240 . can be

In the present invention, for ease of explanation, a number of preset body parts are set as a total of five body measurement parts including the torso (TR) and left and right arms/legs (LA, RA/LL, RL) (refer to FIG. 11a ), but , the body measurement part may be set more subdivided. For example, the body measurement region may be preset as left and right chest, abdomen, left and right upper arms, left and right forearms, left and right thighs, and left and right calves (refer to FIG. 11B ). As the body measurement parts are more subdivided and set, more precise partial body composition measurement is possible.

At least one body measurement part commonly included in the body fat-based standard range for each of the plurality of body parts stored in advance may be determined as at least one candidate body measurement part at the measurement location.

The measurement part determination module 604 compares the impedance value of the detected body fat measurement information with an impedance standard range for each body part among the pre-stored standard ranges of body fat for each body part, and detects the preset plurality of body parts.

At least one second body measurement part having the detected skin conductivity value corresponding to the standard range of skin conductivity for each body part may be selected.

The measurement part determination module 604 compares the subcutaneous fat thickness among the detected body fat measurement information with a standard range of subcutaneous fat thickness for each body part among the pre-stored standard ranges of the plurality of body parts for each body part, and the preset plurality of body parts Among them, at least one third body measurement part having the detected subcutaneous fat thickness corresponding to a standard range of subcutaneous fat thickness for each body part may be selected.

The measurement part determination module 604 may determine at least one body measurement part commonly included in the first to third body measurement parts among the plurality of preset body parts as the at least one candidate body measurement part. .

For example, when the impedance value, the skin conductivity value, and the thickness of subcutaneous fat detected from the partial body fat measurement unit 220 are 300Ω, 80MΩ, and 5 mm, respectively, the measurement site determination module 604 may display the detected body fat information and [ At least one candidate body measurement part may be determined by comparing each of a plurality of pre-stored body fat-based standard ranges for each body part as described in Table 1].

In the above, when determining the position of the electronic device 200 at the measurement position from the measurement position determination module 602, only the left-right movement position and the up-down movement position were considered, but the forward and backward movement positions according to the posture of the electronic device 200 are included. It is possible to discriminate and judge more subdivided body measurement parts.
