The watch type terminal according to the present embodiment includes an electrode unit 340 which collects biometric information of a user by flowing a current through a user's body. The electrode unit transmits current to the user's body, and the watch type terminal forms an impedance value using voltage values at two specific points. Impedance values can be used to provide the user's body fat measurement results.

The watch type terminal 100 according to an exemplary embodiment of the present invention includes a second band 320 for collecting biometric information and a first band 310 for fixing to a user's wrist. 320 includes the electrode unit 340. The second band 320 is electrically connected to the main body 101.

3A to 3C are conceptual views illustrating a structure in which the first and second bands are fixed to the main body.

The first electrode member 341 is formed to be exposed on the first surface of the second band 320, and the second electrode member 342 is exposed on the second surface of the second band 320. It is formed to be. The first and second surfaces correspond to surfaces opposite to each other.

The first surface on which the first electrode member 341 is formed corresponds to a surface in contact with the user's wrist when the watch type terminal 100 is worn on the user's wrist. The first electrode member 341 may be formed to protrude above the surface of the first surface such that the first surface is in contact with the user's wrist.

The second electrode member 342 is formed on a second surface exposed to the outside when the watch type terminal 100 is worn on a user's wrist. The first and second electrode members 341 and 342 may be disposed to overlap each other, but is not limited thereto.

The first and second electrode members 341 and 342 may be made of a metal member capable of flowing a current, and may be made of a pair of metal members as shown in the drawing. For example, the first electrode member 341 is formed of a pair of metal members spaced apart from each other, and the second electrode member 342 is spaced apart from the first electrode member 341. It may be made of a metal member. However, the arrangement of the metal members is not limited thereto.

The electrode member made of the Tx electrode continuously flows current into the body based on a specific control command.

When a closed loop is formed in which the body contacts the first and second electrode members 341 and 342 and current flows, a voltage due to the current flowing through the body is formed. The controller 180 measures the voltage.

For example, if the watch type terminal 100 is worn on the user's wrist, the controller controls the electrode unit 340 to flow the current, or controls to flow the current at a predetermined time interval, When it is detected that both the first and second electrode members 341 and 342 are in contact with the body, the current may be controlled to flow.

3A and 3B, the second band 320 may be fixed to the main body 101. The protrusion 321b formed at one region of the end of the second band 320 is connected to the second fixing portion 321a protruding from the main body 101. The second band 320 includes a flexible circuit board 181 ′ electrically connected to the first and second electrode members 341 and 342. The flexible circuit board 181 ′ is formed in the second band 320. The flexible circuit board 181 ′ extends from the second band 320 and is inserted into the main body 101. Although not specifically connected to the drawing, the flexible printed circuit board 181 ′ is electrically connected to both the first and second electrode members 341 and 342.

Meanwhile, referring to FIG. 3C, the first band 310 may not include a structure electrically connected to the main body 101.

4A to 5B are conceptual views for explaining the principle of body fat measurement. Additionally, referring to FIGS. 4A and 4B, the electrical conductivity of fat and the muscle conductivity of muscle are different from each other. Fat-fat contains the most body water in the body, it has a good conductor property when a small current flows, and body fat has an insulator property in which current does not flow well because it contains little water. Body weight is determined by the sum of body fat and lean body mass, and lean body mass is formed by the sum of muscle mass and inorganic mass.

Therefore, even when the same current flows, a difference in the measured voltage value occurs according to the amount of fat and muscle included in one region of the body through which the current flows. Fats have insulators that do not flow well and have high impedance. Muscles have the same properties as conductors with good current and low impedance. That is, the controller 180 can obtain a body fat measurement result of the body using the impedance value.

The frequency can be adjusted to measure the components of the body. Membranes of the cellular components of the body act as a resistive membrane and have a characteristic of low impedance when the frequency is increased. That is, low frequencies pass only outside the tissue of the cell, while high frequencies form a path into and out of the tissue of the cell. For example, about 1 KHz current can measure the conductivity of the epidermal skin, and about 50 KHz can measure the impedance of components of the body. Accordingly, the first and second electrode members 341 and 342 use a high frequency to allow current to reach the cell.

In other words, when the body is viewed as a resistor and a low current of a specific frequency (about 50 KHz) is flowed between the first and second electrode members 341 and 342, a voltage is formed. Accordingly, the impedance information of the part of the body through which current flows between the first and second electrode members 341 and 342 may be obtained using voltage and current. For example, the controller 180 may obtain an impedance value of a part of the body between the first and second electrode members 341 and 342, and may include user information (age, gender, height, weight, etc.). Based on the correction of the impedance value, it is possible to form a body fat measurement result including muscle mass and fat mass.

5A and 5B are conceptual views illustrating a control method of a watch type terminal according to an embodiment of the present invention.

Referring to FIG. 5A, an application for providing the body fat measurement result may be installed in the watch type terminal 100 according to an exemplary embodiment of the present invention. When the application is executed, the controller 180 may control to store user information (age, gender, height, weight, etc.) of the user in the memory 170.

The controller measures a voltage by flowing a current when a user contacts a part of a body (for example, a finger) with the second electrode member 342 while the first electrode member 341 is in contact with a user's wrist. . As shown in the figure, current passes through one region of the user's body by the first and second electrode members 341 and 342 contacting one wrist and one finger, respectively. For example, when the watch type terminal 100 is worn on the right wrist and the left hand is brought into contact with the second electrode member 342, the voltage of the current flowing from the right arm to the left hand through both legs may be measured. The display unit 151 may output a notification screen indicating a measurement state while the current is output.

The controller 180 calculates a body fat measurement result based on the impedance value and user information stored in the memory 170. The display unit 151 outputs the body fat measurement result 502. The controller 180 may control the haptic module 153 to output a vibration while measuring the impedance value.

Referring to FIG. 5B, when the finger contacts the second electrode member 342 while the time information 501 is output on the display unit 15, current flows through the body. Outputs the body fat measurement result 502 using. The controller controls the display unit 151 to output the time information 501 again after a preset time t passes after the body fat measurement result 502 is output.

The display unit 151 may continuously output the time information 501 while measuring the voltage.
