DETAILED DESCRIPTION

[0016] The conventional intelligent pillow for brain-computer interaction usually sets various components inside the pillow, and arranges an array of electrode heads on the upper surface of the pillow for electric stimulation of the human head, trying to ensure that the human head can keep in contact with the electrode heads no matter how the human head moves on the pillow by the number of electrode heads. Since the components are arranged inside the pillow and the electrode heads are fully laid on the upper surface of the pillow, the elasticity of such a pillow is very poor, and the comfort of the human head on it is very low. Even if the person falls asleep in an unintentional state, the head will also be moved away from the pillow. Moreover, the electrode heads arranged on the surface are fixed, and the pressure on the pillow is different in different states such as before falling asleep, light sleep state and deep sleep state. Therefore, even if the number of electrode heads is sufficient, the electrode heads still cannot keep close contact with the human head at all times, and the effect of releasing electric stimulation is also poor.

[0017] In order to better understand the purpose, structure and function of the present application, the specific embodiments of the "intelligent pillow" of the present application will be further described in detail below in combination with the drawings.

When the smart pillow works, the human head falls in the pillow groove and contacts the electrode heads 304, the torque sensors collect the contact torque data of the electrode heads 304 and the head in real time and return the contact torque data to the central controller, the central controller processes the obtained contact torque data and drives the lifting platform 302 to move up and down through the driving assembly 301, so that the contact torque always remains at a set torque value, and the electrode heads 304 and the human head can always maintain close contact to ensure that the electric stimulation is always released in place, and the user does not feel uncomfortable due to the hard headrest. Long-term and convenient nerve regulation is achieved, which helps to relieve stress and fall asleep.

[0019] It should be noted that the central controller in the embodiment is a central control board in the prior art which integrates functions such as connection of power supply, timing, processing and storage of information, issuance of control instructions, wireless signal connection and transmission, similar to a computer host or motherboard, and has high intelligence.
