The humidity sensor 12 is a sensor for measuring a skin resistance value change caused by a flow of an external current passing through sweat glands. That is, since the resistance value of the internal tissue of the skin changes due to the action of the sweat glands due to the antagonistic action of the sympathetic and parasympathetic nerves, the body senses the feelings such as fear, anger, The state can be predicted, and the stress is also predictable. By way of example, the humidity sensor 12 may be, but is not limited to, a Galvanic Skin Response (GSR) sensor.

The dongle 61 may include a wireless communication unit 62, an MCU 63, and a USB port 64. As an example, the dongle 61 may be a dongle that performs a GFSK (Gaussian frequency-shift keying) RF communication function for data communication in the 2.4 GHz ISM band, which is a multi-channel wireless communication system. Thus, the sleep state signals collected from the plurality of signal collecting units 40 can be received.

The sleep state may include an arousal state, a non-REM sleep state, and a REM sleep state.

The awake state refers to a state in which the subject is awake and the EEG occupies more than 50% of the EEG with a frequency of 8 to 12 Hz.

The non-REM sleep state can be divided into four stages. The first sleep phase is a sleeping elevation phase, in which the alpha waves of the EEG are reduced to less than 50% and the mixing frequency is low. It can easily wake up during the first sleep phase. The second sleep phase is characterized by sleep spindles and K-complex waves. In the second sleep phase, a stronger stimulus than the first sleep phase can be awakened. In the third and fourth sleep stages, the frequency of the EEG decreases gradually as the depth of the water surface increases. The third sleep phase is the stage where the heights above 75 uV and the frequencies below 2 Hz occupy 20 ~ 50%, and the fourth sleep phase means the stage where the proportion of the waves exceeds 50%. In the third and fourth sleep stages, a stimulus that is greater than the second sleep stage can be awakened. The first and second sleep stages may be referred to as shallow sleep, and the third and fourth sleep stages may be referred to as continental sleep, delta sleep, or deep sleep. If there is a slight movement of the body during the deep sleep of the third and fourth sleep stages, the sleep state can be a shallow sleep phase.

The brain waves in the REM sleep state are similar to the brain waves in the first sleep phase in the non-REM sleep state, but sawtooth waves appear. Changes in heart rate in REM sleep state are similar to arousal, but muscle tension is minimized. In other words, it can not move the body actively while sleeping, but the EEG and physiological responses are active, and the REM sleep state is also called the paradoxical and active sleep state.

The display unit 68 may display the sleep state determined by the sleep state determiner 67 so that the user can confirm the sleep state.

The alarm unit 69 can provide an alarm service according to the sleep state determined by the sleep state determiner 67. For example, if the subject is an infant, if the subject's sleep state is determined to be awake, the parent may beep to alert the child that he has woken up.
