The ear jack has a pin for outputting an audio signal (ECG signal) measured by the headset 50 to the ECG sensor 104 in addition to a pin (terminal) for outputting an audio signal to the headset.

The mobile terminal 100 to which the headset plug is connected may include a contact detector 102 and a multiplexer (MUX) in addition to the audio codec 101 and the controller 180 which are basically included in the mobile terminal of FIG. 1. 103 and ECG sensor 104 are further included. However, when the device electrode is not disposed in the mobile terminal, the multiplexer 103 is unnecessary.

The touch detector 102 is a part for detecting whether the ear or the user's hand is in contact with the headset 50 and the mobile terminal 100. To this end, the device electrode 100a is disposed not only at the headset 50a on the outside of the headset but also at a position where the user's hand frequently contacts the mobile terminal.

5 is an example of a position where a device electrode is disposed in a mobile terminal.

The device electrode is attached in a pad shape to a portion where the user easily touches the mobile terminal, and is disposed on the left and right sides corresponding to the horizontal or vertical direction of the mobile terminal in order to distinguish between the right hand and the left hand contact.

The controller 180 controls the audio codec 101, the multiplexer 103, and the ECG sensor 104 according to the touch detection signal sensed by the touch detector 102.

The audio codec 101 outputs an audio signal (music) through an internal sound output module (speaker) 152 when a user selects a predetermined music-related application, for example, an MP3 function using a mobile terminal, and generates a headset. When the plug of 50 is connected to the ear jack, it detects this and plays the role of outputting the audio signal to the ear jack which can be output to the headset 50.

The multiplexer 103 performs a function of transferring the electrical signal (the body signal) detected by the headset 50 or the mobile terminal to the ECG sensor 104 according to the control (MUX_CONT) of the controller 180.

The ECG sensor 104 measures a user's electrocardiogram by using a potential difference of an electrical signal detected from at least one electrode disposed on one side of the headset 50 or the mobile terminal. In general, the electrocardiogram has a potential difference of an electrical signal depending on the measurement position. For example, parts close to the heart, such as the hand, have a high potential difference, so the ECG waveform is well detected, but parts such as the ear have a low potential difference because they are far from the kidney, and thus the ECG waveform may not be detected well.

Therefore, the controller 180 distinguishes whether the contact position is a hand, an ear, or a hand, even if it is both hands or one hand, and outputs different control signals CONT to the ECG sensor 104, thereby providing an ECG sensor 104. ) Amplifies the ECG signal with a gain determined by the control signal CON to detect an ECG waveform. The detected ECG signal is output to the controller 180 again and displayed on the display unit 151 for the user to see.

In particular, in the present invention, the controller may be configured as an MCU or an application processor separately from the controller 180 shown in FIG. 1. This is for the load of the controller 180, which is connected to the controller 180 shown in FIG. In addition, the number of pins (terminals) of the ear jacks is separated for the audio signal and the ECG signal.

And, when the ear contact and the hand contact occurs a lot, the present invention processes the contact according to the priority. For example, when two or more ear and hand contacts occur, for example, when a hand contacts an electrode of a mobile terminal while wearing a headset, priority may be given to an electrode on the ear.

6 is an example of a gain adjusting unit provided in the ECG sensor 104.

Referring to FIG. 6, the switch SW switches one of three resistors R1 to R3 according to the control signal CONT output from the controller 180. The amplifier AMP amplifies the input signal (the electrical signal output from the electrode) at a gain determined by the switched resistor. In this case, R1 to R3 represent both ear contact and hand contact (headset or terminal).

Referring to FIG. 4, operations performed to listen to music, check a user's health state, and control an operation of a mobile terminal in an ECG sensor application apparatus using a headset according to an embodiment of the present invention configured as described above will be described.

1. Listen to music and check your health

When the user selects a predetermined music-related application, for example, an MP3 function using the mobile terminal, the audio codec 101 outputs an audio signal (music) through an internal sound output module (speaker) 152.

In this state, when the plug of the headset 50 is connected to the ear jack of the mobile terminal 100, the audio codec transmits the audio signal to the internal sound output module (speaker) 152 according to the ear jack detection signal EARJACK_DET. The audio signal is output to the ear speaker (not shown) of the headset 50 by outputting through the ear jacks without outputting, so that the user can listen to music while wearing the headset.

When the user executes a predetermined application for measuring ECG while listening to music, the headset electrode 50a attached to the inside of the headset 50, that is, the ear contact portion, is measured at both ears of the user. The biological signals EAR_R and EAR_L (hereinafter abbreviated as ECG signals) are output to the ear jacks of the mobile terminal. The touch detection unit 102 detects that the current user is wearing both headsets from the ECG signals EAR_R and EAR_L received through the receiving pin (terminal) of the ear jack, so that the contact point with the headset is both ears. The detected touch detection signal is output to the controller 180.

The control unit 180 outputs the control signal MUX_CONT to the multiplexing unit 103 according to the touch detection signal output from the touch detection unit 102 and controls the amplification ratio of the ECG signal to the ECG sensor 104. The gain control signal CONT is output. The multiplexer 103 outputs the ECG signals EAR_R and EAR_L applied through the ear jacks to the ECG sensor 104 according to the control signal MUX_CONT.

Therefore, the ECG sensor 104 amplifies the ECG signals EAR_R and EAR_L input through the multiplexer 103 at different amplification rates according to the gain control signal CONT output from the controller 180. The detected ECG signal is output to the controller 180, and the controller 180 displays the corresponding ECG signal (electrocardiogram waveform) on the display unit 151.

As such, the present invention physically separates the audio signal and the biosignal (ECG signal) through the internal pins (terminals) of the ear jack. By detecting and displaying the ECG waveform of the user, ECG measurement and music can be easily performed.

On the other hand, if the user wears the headset 50 while not executing the MP3 function, and runs the application for ECG measurement, the headset 50 is used only for the purpose of ECG measurement.

2. Motion control of mobile terminal based on ear contact and hand contact of headset

As described above, electrocardiogram measurement is made via an electrode 50a attached to the inside of the headset 50. However, the control related to the operation performed in the mobile terminal, such as listening to music or receiving a call, is basically performed by the contact of the headset electrode 50a located outside the headset 50. However, since the headset can be worn only on either side or one side, it can be said that it is mainly made by the combination of the electrodes 50a and 50b disposed on the headset 50. In addition, the present invention can use the device electrode (100a) shown in Figure 4 for the operation control of the mobile terminal, the priority used for the operation of the mobile terminal has a high electrode contact in the headset 50, disposed in the mobile terminal The device electrode 100a is low.

Therefore, even if the user touches the headset electrode 50b with one hand while touching the device electrode 100a with the other hand while the user wears the headset 50, the operation of the mobile terminal according to the contact of the headset electrode 50b. This is controlled. However, when the headset electrode 50b is touched without touching the device electrode 100a while the headset 50 is worn, the operation of the mobile terminal is controlled according to the device electrode 100a.

7A and 7B illustrate an example of controlling the operation of the mobile terminal according to the ear contact and the hand contact of the headset.

As shown in FIG. 4, the touch sensing unit 102 measures an ECG measured by an electrode 50a attached to the inside of the headset 50, an electrode 50b attached to the outside, and an electrode 100a attached to the mobile terminal. Depending on the magnitude of the voltage of the signal, it may be known whether the user wears the headset 50 or touches his hand. This is because the ECG signal measured at the ear and the ECG signal measured at the hand are different, and further, the hand contact on the surface of the headset and the mobile terminal may be different.

Accordingly, the controller 180 controls (plays, fast forwards, rewinds, stops, and other) MP3 playback or call operation (call connection, call termination) according to the touch detection signal output from the touch detection unit 102. And lock control (screen lock release).

Hereinafter, an example of controlling the MP3 playback and the call connection operation according to the ear contact and the hand contact of the headset will be described.

As shown in FIG. 7A, taking off the headset 50 in a state where no function is being executed, no au operation occurs. However, when the user wears the headset 50 while the MP3 function is executed, the MP3 playback is paused when the user wears the headset 50, and when the user wears both headsets again, the MP3 is played again.

On the other hand, when the user wears both headsets and one hand touches the electrode 50b (or electrode 100a) disposed on the side of the headset, the controller 180 plays the MP3 according to the touch of the right electrode or the left electrode. Forward or reverse with forward arm.

If the user double-contacts the headset electrode 50b (or electrode 100a) with one hand wearing both headsets, the controller 180 stops or plays the MP3. In this case, the double contact may be divided into a right or left electrode. In addition, if the user wears only one headset while wearing both headsets, the controller 180 stops MP3 playback.

The controller 180 may perform a call reception process according to the ear contact and the hand contact of the headset. As shown in FIG. 7B, when a user receives a call while wearing both headsets (one or both), the call is immediately connected and when a call is received while the user wears both headsets (one or both). Perform a call connection, and then perform a call waiting when one hand (electrode 50a or 100a) is touched (a call is performed again). After that, when the user takes off the headset, the controller 180 ends the call.

8 is another embodiment of an apparatus for measuring biometric information using a wired headset according to an embodiment of the present invention. In particular, the embodiment shown in FIG. 4 separates the audio signal and the ECG signal by increasing the number of pins of the ear jack, but the embodiment of FIG. 8 separates the TX / RX signal by frequency band instead of using the existing ear jack. A duplexer 105 is used.

That is, the duplexer 105 outputs an audio signal of 20 hz to be transmitted to the ear jack, and transmits the 20 GHz ECG signal received from the headset 50 through the ear jack to the touch detector 102. Since other operations are the same as in Fig. 4, detailed description thereof will be omitted.

It detects the contact (ear or hand point) and outputs a touch detection signal to the MCU 50-1. The MCU 50-1 determines the type of contact (ear or hand) according to the touch detection signal output from the touch sensing unit, and then controls a control signal MUX_CONT and an ECG sensor for controlling the multiplexer 50-3. The control signal CONT for controlling the gain of 50-4) is output, respectively.

The multiplexer 50-3 is operated according to the control signal MUX_CONT so that the ECG signal detected by the electrode 50a is output to the ECG sensor 50-4, and the electrode 50b is disposed on the side of the headset. Signals detected at (Hand R, Hand L) is output to the ear jack of the mobile terminal (100).

The ECG sensor 50-4 amplifies the ECG signal detected by the ear according to the gain control signal CONT output from the MCU 50-1, and then outputs the result to the MCU 50-1. 50-1) outputs the ECG signal, amplified by the ECG sensor 50-4, to the ear jack of the mobile terminal through the serial interface.

Therefore, the control unit 100 of the mobile terminal displays the ECG waveform received through the ear jack on the display unit 151, and when the MP3 function is being executed or a call is received, it is detected by the electrode 50b of the headset. As shown in FIGS. 7A and 7B, using the hand detection signals Hand R and Hand L transmitted through the jack and the hand detection signals Hand R and Hand L detected by the electrode 100a of the mobile terminal. Control various operations (MP3 playback, call reception and screen lock control) of the mobile terminal.

4 to 9, the electrode 50b of the headset 50 and the electrode 100a of the mobile terminal are used for detecting an ECG sensor and a key for controlling the operation of the mobile terminal. It can be seen that the use dome, in particular, if the ECG sensor is embedded in the headset 50 can be seen that the user's electrocardiogram (ECG signal) in the headset is measured and transmitted to the mobile terminal.

The method and structure of the ECG sensor using the headset illustrated in FIGS. 4 to 9 are similar to the case in which the headset is wired to the mobile terminal, but the present invention is not limited thereto. do.

That is, the electrode 50a disposed inside the headset outputs the user's biosignal, that is, the ECG signal, and the electrode 50b disposed outside thrusts the hand contact (Hand-R, Hand_L) of the user. The touch detection unit 51-2 detects a hand contact or an ear contact from the signals output from the electrodes 50a and 50b, and outputs a contact detection signal to the DSP 51-2, and the ECG sensor 51-3 In accordance with the gain control signal of the DSP 51-2, the ECG signal measured by the electrode 50a is amplified and output to the DSP 51-2.

Accordingly, the DSP 51-2 outputs the ECG signal measured by the ECG sensor 51-3 to the mobile terminal 100 through the wireless communication unit 51-1, and the controller 180 controls the wireless communication unit ( The ECG waveform received through 110 is displayed on the display unit 151.

In addition, when the MP3 function is executed and predetermined music is being played by the ear speaker of the wireless headset 51, as shown in FIG. 7A, when the user contacts the electrode 50b or changes the wearing state of the headset, The touch detector 51-4 determines the hand contact (Hand_R, L) and the ear contact (Ear_R, Ear_L) and outputs it to the DSP 51-2, and the DSP 51-2 receives the touch detector ( An operation control signal for controlling the operation of the mobile terminal according to the touch detection signal output from 51-4) is generated and transmitted to the mobile terminal through the wireless communication unit 51-1.

In addition, the user wears the headset or wears the headset. When a call is received while listening to music, as shown in FIG. 7B, the call reception operation is performed according to the contact state between the two electrodes 50a and 50b of the wireless headset 51.

Therefore, the present invention can simultaneously perform music listening and ECG measurement using a headset.

Thereafter, when a user's hand contact occurs at an electrode 50b located outside the headset and a detection signal (Hand_R, Hand_L) is received through the ear jack (S15), the controller 180 determines the hand contact type through the contact detector. Then, according to the hand contact information, the operation of the MP3 function of the mobile terminal (Play, Forward, Reverse, Pause and others) is controlled (S16).
