The present invention detects a movement of a user lying on an electric field forming mat continuously by a sensor, thereby detecting a movement of the user and detecting a movement of the user. Is determined to have entered the sleep period, a signal is sent from the body movement determination unit to the electric field output control unit, and the electric field output is varied in the mat by a command signal based on a program preprogrammed in the electric field output control unit An electric field-operated sleep assist device capable of detecting sleep onset in which an output signal is transmitted and a frequency of a wavelength corresponding to REM sleep and non-REM sleep is sequentially generated by an electric field generated from the mat by the output signal. .

In general, “sleep” is composed of two different properties, “REM sleep” and “non-REM sleep”. “REM sleep” is a sleep accompanied by rapid eye movement, and the eyeball moves even when sleeping, and the brain is a shallow sleep close to awakening. On the other hand, the “non-REM sleep” is a sleep that is not a REM sleep and is in a state of a good sleep, and the “non-REM sleep” is further divided into four stages according to the depth of sleep.

During sleep of the “REM sleep” and “NREM sleep”, there are a REM and a non-REM sleep cycle that occur with an almost periodic rhythm. As shown in FIG. 1, it takes about 90 minutes to go through a non-REM sleep and enter a REM sleep, which is called “sleep unit”. In the case of an adult, a person who sleeps for 8 hours per night repeats “REM sleep” and “Non-REM sleep” 5 times for sleep units and 4 times for 6 hours. At that time, it becomes easy to wake up every time REM sleep ends, that is, every 90 minutes.

Brain waves are potential changes observed in the brain, and it is generally said that a living body emits four types of brain waves, α waves, β waves, θ waves, and δ waves, depending on the daily living environment. (However, the term “out” means that “a waveform containing a lot of frequency components called α waves” is observed ”). Each type and frequency of the electroencephalogram and the state of the living body at that time have a standardized characteristic as shown in FIG.

The present invention provides a wavelength corresponding to the REM sleep and the non-REM sleep in a period of 90 minutes when the user detects a "sleeping period" by a sensor capable of detecting body movement after falling asleep on an electric field forming mat. This frequency is generated on the mat on which the user is lying, and the brain wave is induced to the frequency according to the sleep depth of the user, thereby contributing to the user's deep sleep. This is an electric field-operated sleep aid that can detect sleep onset. Hereinafter, the electric field operation type sleep aid capable of detecting sleep onset according to the present invention will be described in detail with reference to the drawings. As the sensor that can detect the user's body movement, which is a main component in the present invention, either an acceleration sensor or a radio wave sensor can be employed.

First, a sensor that uses an acceleration sensor as a sensor capable of detecting body movement will be described as a first embodiment of the present invention. That is, in FIG. 3, 1 is a controller, and the controller 1 has an acceleration sensor 2 connected to a body motion determination unit 3, and the body motion determination unit 3 is connected to an electric field output control unit 4. The electric field output control unit 4 is formed by being connected to the electric field output unit 5, and the controller 1 is integrally connected and fixed to the edge of the electric field forming mat 6. The acceleration sensor 1 can detect the movement of the user lying on the mat 6 in the XYZ directions.

The mat 6 is provided with an electric field generating section 7 made of an electric field forming conductor, as in a conventionally known potential treatment device, and in response to a command signal from the electric field output control section 4 of the controller 1. In addition, an electric field is generated from the mat 6 via the electric field output unit 5, and the electric field generated from the mat 6 matches the cycle of REM sleep and non-REM sleep that reach the user's sleep period, mid-sleep period, and late-sleep period. Thus, by sequentially generating frequencies of wavelengths corresponding to REM sleep and non-REM sleep, the user's brain wave on the mat 6 is induced to change to an optimum frequency for sleep.

The mat 6 includes an electric field generating unit 7 made of a conductive wire for forming an electric field, and a controller 1 equipped with an acceleration sensor 2 for detecting a body movement of a user lying on the mat 6.

Based on the motion determination unit 3, the result determined by the body motion determination unit 3, the electric field output control unit 4 that controls the electric field generation in the mat 6, and the mat 6 according to the command from the electric field output control unit 4 Electric field output units 7 for generating electric fields are respectively installed. In the figure, 8 is a power supply unit for turning on the power to the controller 1, and 9 is a power cord.

Based on the result determined by the body movement determination unit 3, the electric field output control unit 4 that controls the generation of the electric field in the mat 6 is adapted to the REM sleep and non-REM sleep cycles leading to the sleep onset, the middle sleep and the late sleep. In order to sequentially generate the frequency of the wavelength corresponding to the REM sleep and the non-REM sleep, a preprogrammed program is incorporated so that the electric field output can be changed, and the electric field output is output to the mat by a command signal based on the program. An output signal that fluctuates is transmitted.

First, after the controller 1 is turned on so that an electric field can be generated on the mat 6, when the user lies down on the mat 6 to sleep, the acceleration sensor 2 is used. The body motion signal detected by the acceleration sensor 2 is continuously sent to the body motion determination unit 3 during this period, and the acceleration sensor indicates that the user's motion has decreased. 2, the body movement determination unit 3 determines that the user has entered the sleep period, and a signal is sent from the body movement determination unit 3 to the electric field output control unit 4, so that the electric field output control unit 4 In response to a command signal based on a pre-programmed program, an output signal for changing the electric field output is transmitted to the mat 6 via the electric field output unit 5, and electric power generated from the mat 6 by the output signal is transmitted. By sequentially generating the frequency of the wavelength corresponding to the REM sleep and the non-REM sleep in accordance with the cycle of the REM sleep and the non-REM sleep leading to the sleep onset, the middle sleep and the late sleep, the brain wave of the user on the mat 6 is generated. It is induced by changing the frequency to the optimal frequency for sleep.

In response to a command signal from the electric field output control unit 4 of the controller 1, generation of an electric field is commanded to the electric field generation unit 7 of the mat 6 via the electric field output unit 5. A command signal is sent in accordance with a pre-programmed program so that a frequency of a predetermined wavelength is generated in the mat 6. That is, as shown in FIG. 1, it takes approximately 90 minutes to go through REM sleep and enter non-REM sleep. In the case of an adult, as described above, a person who sleeps for 8 hours per night repeats the REM sleep and non-REM sleep for 5 sleep units and 4 times for 6 hours. At that time, it becomes easy to wake up every time the non-REM sleep ends, that is, every 90 minutes. In the present invention, after the user has fallen asleep on the mat 5 (after the falling asleep period is detected), a θ wave (4) can be induced in a 90-minute cycle according to the depth of sleep. ˜7 Hz) and δ waves (0.5 to 3 Hz) are generated by electric field operation, and are guided to the brain wave frequency optimal for the user's sleep by each frequency.
