According to the present invention, the mobile terminal can be configured to include a PPG sensor and a pressure sensor in a signal input unit configured to receive a control signal and configured to input a control signal, thereby collecting information capable of calculating a blood pressure without using an additional space. In addition, since it is formed integrally with the signal input unit, the biometric information for calculating the blood pressure can be collected while the specific function is performed. Therefore, a separate sensor module for measuring blood pressure is not required.
In addition, since some electrode portions of the ECG module for collecting ECG information are disposed adjacent to the electronic components of the mobile terminal, it is unnecessary to install an additional sensing module and there is no fear of being covered by a case mounted on the main body. In addition, when electronic parts are used, biometric information can be collected.

[ Also, although not specifically shown in the drawings, the sensing module 320 includes a pressure sensor. Here, the pressure sensor may be substantially the same as the pressure sensor of FIG. 2B. The controller 180 may measure the blood pressure based on the measured pulse wave and pressure.

The first region 331 may have a predetermined width so that the user's hand may contact the second region 332 and the second region 332 may surround the edge of the first region 331. The first and second regions 331 and 332 are exposed to the outside of the mobile terminal 100, and the shapes are not limited to those shown in the drawings.
The sensing module 330 can recognize the fingerprint in an active capacitive manner by using the first and second regions 331 and 332. An electrical signal is transmitted from the second region 332 made of metal, and the transmitted electrical signal is reflected by the bending of the fingerprint. The transmitted electrical signal passes through the dead skin (12) of the finger and is reflected from the live skin (11) and enters the second region (332).

4C is a view showing the pulse wave measured while the pressure is applied.
FIG. 4C shows the pressure applied with time, and FIG. 4C shows the pulse wave detected by the PPG sensor as a waveform of voltage change with time.
The light emitting unit 313 and the light receiving unit 314 constitute a PPG sensor. The PPG sensor irradiates light of a specific wavelength band to the body, and measures a signal indicating a pulse wave segment generated according to a heartbeat with a signal that detects reflected or transmitted light. When light is emitted from the light emitting unit 310, absorption of light occurs in the blood, bone, and tissue, and some light is transmitted to the water sensing unit 314. The extent to which light is absorbed is proportional to the amount of skin, tissue, and blood in the path of light travel, and is a component that does not change except for changes in blood flow due to atrial beats. Therefore, the amount of light absorbed is proportional to the change in blood flow. Since the transmitted light detected by the light receiving sensor unit 314 is received by being subtracted by the amount of light absorbed by the finger, the amount of transmitted light is also reflected by the reflected light. Therefore, it is possible to detect the blood volume change synchronized with the atrial beat by measuring the light amount of the light receiving unit 314. [
The controller 180 estimates the blood pressures of the part to be examined based on the time points of the detected pulse waves and the time differences of the pulses of the filtered pulse waves. The systolic blood pressure (systolic BP) and the minimum blood pressure (diastolic BP) can be estimated as the blood pressure having the maximum size among the estimated blood pressures. Further, the present invention is not limited to this, and other blood pressures such as mean blood pressure (mean BP) can be estimated using estimated blood pressures.

[ However, the type of light emitted from the light emitting unit 341 is not limited to the laser.
