The user terminal may perform wired or wireless communication with the sleep tracking server, and may directly communicate with the smart mattress 1 wired or wirelessly. The wired/wireless communication method is not limited, and a commercially available method can be used.

The sleep tracking server or user terminal includes a sleep determination unit that determines whether the user is in a REM sleep or a NREM sleep state by tracking the user's sleep based on the user's motion and biometric signals detected by the operation of the sensor unit. do.

First, a smart mattress according to an embodiment of the present invention will be described. The smart mattress includes a mattress 10 that supports the body of a user (sleeper), a cover 30 stacked on the mattress 10, and a sensor unit 20 provided between the mattress 10 and the cover 30. Includes. When the user is seated on the cover 30, the pressure is transmitted through the cover 30 so that the sensor unit 20 operates, and the user's movement and bio-signals are tracked (tracking) so that the sleep state can be measured. do.

In the mattress 10, a cover 30, which is in direct contact with the user's human body (a separate sheet may be further stacked) is stacked, and between the lower portion of the cover 30, that is, between the mattress 10 and the cover 30. It includes a sensor unit 20 provided. Here, the mattress 10 may be made of at least one of polyurethane, latex, and synthetic resin. However, it is not limited to these materials, and natural fiber materials, elastic members, and the like may also be used. The cover 30 may be provided with a sheet or the like that is seated by the user and is in contact with the body.

The sensor unit 20 is provided between the mattress 10 and the cover 30, detects the user's movement, and senses at least one of information on the user's heart rate, pulse rate and respiration volume, and sound. The sensor unit 20 may measure the user's sleep state in real time or periodically during sleep. The sensor unit 20 may increase the accuracy of determining the sleep state by providing a plurality of sensors.

The sensor units 20 and 130 include a pressure sensor, an air sensor (temperature sensor, humidity sensor), a heart rate sensor, a pulse sensor, an FSR film sensor, a noise measurement sensor, and the like. The measured values obtained from the sensor units 20 and 130 may be transmitted to an external sleep tracking server and/or a user terminal using the wireless communication unit 140 through the control unit 100.

The pressure sensor can measure the pressure exerted from use. The pressure sensor is composed of a load cell, a plurality of upper electrodes disposed in parallel at a predetermined distance apart in the longitudinal direction, and a plurality of lower electrodes disposed in parallel at a predetermined distance apart in the transverse direction so as to cross each other with the plurality of upper electrodes. It may include an electrode and a dielectric layer provided between the upper electrode and the lower electrode. The pressure sensor may be provided with a touch sensor, a piezo sensor, and an FSR film sensor capable of tracking the distribution and distribution of the user's weight.

The heart rate sensor and the pulse rate sensor measure the user's heart rate and/or pulse rate, respectively. The noise measurement sensor measures at least one of a sound generated by a user and a respiration volume. That is, the noise measurement sensor detects the user's snoring sound, lice sound, drooling sound, turning sound, breathing sound, and the like. The atmospheric sensor may measure the temperature and humidity around the surface of the cover 30. In this case, the control unit 100 may increase accuracy by receiving a noise value measured by the user's sound from the noise measurement sensor, removing noise, and analyzing only the noise generated by the user.

In addition, a separate input unit 110 may be provided in the smart mattress. User information and new user information can be directly input through the input unit. For example, it may be configured with a touch panel provided in a smart mattress. Information input through the input unit may be transmitted to the outside through a wireless communication unit through a control unit.

Meanwhile, the sleep tracking server or the user terminal may perform the function of the input unit, and in this case, the input unit of the smart mattress may be omitted.

Next, in the smart mattress system, the sleep tracking server or user terminal tracks the user's sleep based on the user's movement and biometric signals sensed by the operation of the sensor unit to track a REM sleep or a NREM sleep state. It may include a sleep determination unit that determines whether or not (on the other hand, the sleep determination unit may exist in the smart mattress itself, which is not excluded from the present invention). The sleep tracking server or user terminal may have a storage unit that stores sensing information transmitted from the smart mattress in real time or periodically.

Alternatively, the user terminal may be provided with the sleep determination unit. The sleep determination unit may be performed by installing a sleep tracking application. The user terminal may receive sensing information through a sleep tracking server, or may receive sensing information directly through wireless communication with a smart mattress.

The sleep determination unit may determine the non-REM sleep state by dividing it into four stages. Here, REM sleep is a shallow sleep that is close to waking, and is a stage of sleep that is divided by the rapid movement of the eyeball.

When non-REM sleep is divided into four stages, the first stage is drowsy, drowsy, heart rate, and respiratory rate slightly decreased, and a very short period of sleep, in which brain waves change from beta waves to alpha waves. In addition, the second stage is a section where you can hardly feel heart rate, respiratory rate decrease, body temperature decrease, stimulus of the surrounding environment, and you can wake up if you try, and you fall deeply into sleep. This is a section in which fusiform and K-complex brain waves appear. Stage 3 is a state in which there is no response to parasympathetic nerves or stimulation, and is a state of deep sleep, complete relaxation of the musculoskeletal system, snoring, etc., at this time, sleep disorders such as sleepwalking and night terror may occur, which occur unconsciously and are not recognized. In the fourth stage, deep sleep, heart rate and respiration rate decrease by 20-30% compared to awakening, muscles are very relaxed, dreams are possible, and growth hormone is secreted. Here, in steps 3 and 4, a delta wave starts to appear, and steps 3 and 4 can be classified by the amount of delta waves.

Determination of REM sleep and non-REM sleep can determine predetermined criteria by analyzing the sensing information of various users into big data. As an example, a number of test subjects' EEG information and smart mattress sensing information are acquired together to make big data, and by comparing and analyzing EEG information and smart mattress sensing results, a reference value for smart mattress sensing in each of REM sleep and non-REM sleep in step 4 can be determined. I can.

The sleep determination unit determines whether or not REM sleep is in comparison with the sensing reference value at each sleep stage using the sensing values transmitted from the sensor units 20 and 130, and determines the number of stages of non-REM sleep, and uses the result as graphs, numbers, characters, etc. Results can be derived or scored.

The sleep tracking server or user terminal may further include an output unit, and the output unit may visually display a result derived from the sleep determination unit, and may display a result using graphs, numbers, characters, colors, and the like. In addition, it is possible to display a sleep determination result that changes according to the lapse of the user's sleep time. Through this, the user can easily know when it was REM/NON REM sleep, total REM sleep time and total non REM sleep time.

On the other hand, the output unit may separately display each sensing information. For example, as shown in FIGS. 5A and 5B, the body pressure distribution and distribution state based on the pressure information received by the smart mattress can be visualized in a 3D graph or It can be visualized and displayed as a color distribution divided by various colors or shades. For example, a hip portion having a high pressure may be indicated in red, and a back and a waist portion having a relatively low pressure may be indicated in blue. In the case of expressing as a three-dimensional graph, a high pressure area can be expressed as a high graph and a low pressure area can be expressed as a low graph. In addition, the output unit may visually display the body pressure distribution and distribution change over time.

Through this, the user can check the degree of movement during sleep, the sleep posture, and the like and correct the sleep posture.

In addition, the output unit may indicate the number of turns during sleep, heart rate, pulse rate, respiration volume (apnea, etc.), snoring time, and the like.

Referring to Figure 3 to describe the operation method of the smart mattress of the present invention, the user inputs user personal information, etc. through the input unit (S10). The sensor units 20 and 130 sense and measure in real time the user's movement and biometric signals lying on the smart mattress. (S20).

The sleep determination unit receives the measured values measured by the sensor units 20 and 130 through the wireless communication unit 140, determines sleep by performing user sleep tracking, and derives the REM sleep/non REM sleep step result values (S30).

If the user deviates from the smart mattress and does not exist (S40), the sleep tracking server and/or the user terminal end the sleep trekking by determining that the sleep is terminated (S50). The output unit displays the sleep tracking result automatically or at the request of the user.

As an example of sleep determination by the sleep determination unit, if the initial heart rate, pulse rate, and respiration rate of non-REM sleep slightly decrease based on the transmitted measurement value, it is determined as the first stage of non-REM sleep, and the heart rate, pulse rate and respiration in the first stage of non-REM sleep. If water, body temperature, etc. decrease, it is determined that the condition in step 2 is met. In the second stage of non-REM sleep, the pressure applied to the pressure sensor increases due to complete relaxation of the musculoskeletal system, and when snoring is detected, it is judged as the third stage of non-REM sleep. In the third stage of non-REM sleep, when the pressure value is higher with the muscles in a very relaxed state, and the heart rate, pulse rate, and respiratory rate decrease by 20 to 30% from the time of measurement when awake (initial), it is judged as the 4th stage of non-REM sleep. .

As described above, the smart mattress according to an embodiment of the present invention has the effect of tracking the user's sleep state in real time to inform the user of the user's sleep state, and to improve sleep habits.

Features, structures, effects, and the like illustrated in each of the above-described embodiments may be combined or modified for other embodiments by a person having ordinary knowledge in the field to which the embodiments belong. Therefore, contents related to such combinations and modifications should be construed as being included in the scope of the present invention.
