A Brief Introduction to the Manufacturing Method of a Smart Pillow

　　As the pace of society accelerates, people are getting less sleep, facing greater life pressures, and experiencing declining sleep quality. Poor sleep quality directly impairs both personal and professional performance, increasing the risk of suboptimal health, insomnia, and even various mental health disorders, thereby exerting a significant impact on individuals’ work and daily life.

　　Current pillow products still rely on traditional technologies and manufacturing processes, which fail to provide a reliable scientific basis for improving sleep quality or for enabling users to acquire and understand their own sleep data. Therefore, there is an urgent need to develop an information-driven, intelligent product capable of capturing human sleep data.

　　In view of the aforementioned issues, technical personnel have developed an intelligent pillow that ensures optimal sleep comfort and monitors the user’s sleep data. To achieve this objective, the intelligent pillow is configured as follows: it comprises a pillow body containing multiple air-column airbags, with the air inlets of the airbags located on the side of the pillow body; furthermore, the pillow body is equipped with sensors for collecting the user’s sleep information, which are connected to a controller.

　　The controller comprises a communication module, a control module, an A/D conversion module, and a power supply module. The power supply module provides power to the A/D conversion module, the control module, and the communication module. The control module is connected respectively to the output ports of the A/D conversion module and the communication module. The communication module communicates with external smart terminal devices, while the input port of the A/D conversion module is connected to the output port of the sensor. The control module transmits the sensed information from the A/D conversion module to the external smart terminal device via the communication module. A pressure sensor is installed inside the airbag; the sensor includes both a pressure sensor and a sound sensor. The pillow body is also equipped with a low-frequency speaker, whose power input is connected via a switch to the power output port of the power supply module, and whose audio input is connected to the audio input terminal on the side of the pillow body.

　　The smart pillow features a memory-foam pillow core and is equipped with both a Wi-Fi communication module and a Bluetooth communication module; the external smart terminal device is a smartphone. The control module of the smart pillow utilizes an MTK6261D chip, while the Bluetooth communication module comprises a CSR8811 Bluetooth chip mounted on a PCB, along with a filter and a crystal oscillator. The PCB is fitted with a power supply interface, PIO interfaces, a UART interface, and an SPI/PCM interface. Additionally, the PCB includes an antenna interface for connecting to the antenna, which is integrated directly onto the PCB.

　　The beneficial effects of the aforementioned smart pillow are as follows: the pillow can adjust its firmness and height via airbags in response to the user’s sleeping position, thereby ensuring optimal sleep conditions; it can also emit customized sounds through a built-in low-frequency speaker. The pillow’s communication module enables interaction with external smart terminal devices, providing users with detailed sleep-related data. Furthermore, pressure sensors and sound sensors allow the pillow to capture real-time information on the user’s sleep, including pressure distribution, breathing patterns, snoring, head positioning, and body movements. In addition, the multi-airbag design enhances the accuracy of sleep-quality monitoring, offering valuable insights for the prevention and treatment of obstructive sleep apnea syndrome, while helping users adopt healthier sleep habits and improve both sleep quality and overall health.
