Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Example 1 A smart seat, such as Figure 1 As shown, it includes a base 1, a support leg 2 fixed to the bottom of the base 1, a seat cushion 3 fixedly installed on the top of the base 1, and a backrest 4 on one side of the seat cushion 3.

[0022] The base 1 is made of high-strength engineering plastic. A support leg 2 is fixed to the bottom 1. The support leg 2 includes a lifting mechanism, and a five-star base is fixed to the bottom of the lifting mechanism. The bottom of the five-star base is equipped with casters 201. In this embodiment, the support leg 2 is a conventional chair leg in the art. An arc-shaped footrest 6 is fixed to the five-star base. The bottom of the footrest 6 is fixedly connected to three support rods of the five-star base. Two second electrode assemblies 601 are installed on the upper surface of the footrest 6. A weighing sensor is installed at the center of the base 1 to measure the user's weight. During use, the user sits on the seat cushion 3 with both feet off the ground to measure their weight.

[0023] A seat cushion 3 is fixed to the top of the base 1. A pressure sensor array 301 is installed on the surface of the seat cushion 3. The pressure sensor array 301 includes 12 pressure sensors, arranged in groups of six, located on both sides of the center line of the seat cushion 3, to monitor the pressure distribution on the user's left and right buttocks. Two vibration motors 302 are installed inside the seat cushion 3, located on one side of each of the two pressure sensor arrays. The vibration motors 302 provide tactile feedback. When the control system detects poor posture or prolonged sitting, it can activate the vibration motors 302 to remind the user to adjust their posture through tactile feedback.

[0024] Multiple body temperature sensors 401 are installed on the side surface of the backrest 4 closest to the human body along the center line of the height direction to monitor the user's back temperature in real time and obtain the user's body temperature health data. Multiple distance sensors 402 are installed on both sides of the body temperature sensors 401 along the height direction. By detecting the distance between the user's left and right back and the backrest 4, and combined with the pressure distribution of the buttocks monitored by the pressure sensor array 301 on the seat cushion 3, the distance sensors 402 on both sides can more accurately determine whether the user's sitting posture is correct. Armrests 5 are fixedly installed on both sides of the seat cushion 3. A first electrode assembly 501 is respectively installed at the front end of the upper surface of each armrest 5. The first electrode assembly 501 and the second electrode assembly 601 form a circuit for measuring the user's body composition parameters. Through bioelectrical impedance analysis technology, body composition data such as body fat percentage and muscle mass are measured. A heart rate sensor 502 is installed on one armrest 5, and a blood pressure sensor 503 is installed on the other armrest 5. Both the heart rate sensor 502 and the blood pressure sensor 503 are located at the front end of the armrest 5 to monitor the user's heart rate and blood pressure data, providing important data support for the user's cardiovascular health monitoring.

[0025] It also includes a control system, located at the bottom of base 1, which processes data from various sensors and enables wireless communication. The control system can receive data in real time from the pressure sensor array 301, body temperature sensor 401, distance sensor 402, heart rate sensor 502, blood pressure sensor 503, and weight sensor, and analyze and process the data. The control system also has a dedicated algorithm for body composition analysis to analyze the user's body composition. Simultaneously, the control system can transmit the processed data to mobile terminal devices (such as mobile phones and tablets) or cloud servers via wireless communication modules (such as Bluetooth and Wi-Fi), allowing users to view their health data anytime and facilitating remote health monitoring and data analysis by medical personnel or health management institutions. The aforementioned smart chair also comes with a companion app. Users can download and install the app on their mobile devices and pair the smart chair with the app via Bluetooth or Wi-Fi. Upon first use of the app, users are guided to input basic information such as height, weight, age, and gender for body composition analysis. An angle adjustment mechanism can also be provided between the backrest 4 and the base 1 to adjust the angle of the backrest 4. The angle adjustment mechanism can use conventional adjustment components in this field. A voice broadcaster can also be installed on the backrest 4 to remind the user of proper posture or prolonged sitting via voice.

[0026] The smart chair provided in this embodiment is used as follows: After the user sits down, the sensors automatically start working, collecting data such as heart rate, body temperature, blood pressure, and weight, and transmitting the data to the control system for processing. When body composition needs to be measured, the user places their hands on the first electrode plate 501 and their feet on the second electrode plate 601 of the foot pedal 6, and immediately begins measuring human body impedance. The control system combines the user's basic information and weight data, and uses a deep neural network algorithm to quickly calculate body composition data. The control system sends all data to the APP, where the user can view detailed health data and posture analysis results, including body composition reports, vital sign trend graphs, and posture scores. When prolonged sitting or poor posture is detected, the control system reminds the user through vibration, voice, etc., and the APP will also issue reminders and provide corresponding suggestions, such as recommending suitable exercise and diet plans based on body composition data.

[0027] Example 2 A smart seat, such as Figure 2 and Figure 3 As shown, the technical solution in this embodiment is basically the same as that in embodiment 1, except that the armrest 5 and the supporting leg 2 in this embodiment are equipped with massage components.

[0028] like Figure 4 As shown, the armrest 5 in this embodiment has a box-like structure. The armrest 5 has a first groove 504 with an upward-facing opening. Two electric telescopic rods 505 are fixed to the bottom wall of the first groove 504. A first mounting plate 506 is fixed to the top of each electric telescopic rod 505. Two symmetrical first massage airbags 507 are fixed to both sides of the first mounting plate 506 along its length for massaging the user's forearms or hands. Multiple massage protrusions 7 are provided on the opposite sidewalls of the two first massage airbags 507. A support plate 508 is provided at the first groove 504. One side of the support plate 508 along its length is hinged to the armrest 5, and the other side is provided with a magnet 8. A magnet 8 is also fixed to the armrest 5, magnetically connecting the support plate 508 and the armrest 5.

[0029] The two support plates 508 open to the sides of the seat, without contacting the body when open. A sponge pad can be fixed to the upper surface of the support plate 508 to increase comfort. When a massage of the arms is needed, the support plate 508 can be easily opened by grasping the sponge pad.

[0030] This embodiment includes two symmetrically arranged box-type support legs 2, such as... Figure 5As shown, each of the two support legs 2 has a second groove 202 on its side near the user's leg. The top and bottom of each second groove 202 have mounting slots, and a slide rail 203 is installed in the mounting slot. An electric slider 204 is slidably connected to the slide rail 203. A second mounting plate 205 is located between the two electric sliders 204, and both ends of the second mounting plate 205 are fixedly connected to the side walls of the two electric sliders 204. Two symmetrical second massage airbags 206 are provided on both sides of the second mounting plate 205 along its height direction for massaging the user's calves. Massage protrusions 7 are provided on opposite sides of each of the two second massage airbags 206.

[0031] A sealing plate 207 is provided at the second groove 202. One side of the sealing plate 207 in the height direction is hinged to the support leg 2 via a hinge, and the other side is magnetically connected to the support leg 2 via a magnet 8. A sponge pad can also be provided on the outer surface of the sealing plate 207 to increase comfort. At the same time, when it is necessary to massage the calf, the sealing plate 207 can be easily opened by grasping the sponge pad.

[0032] During design and manufacturing, an additional massage airbag can be added to the surface of the first mounting plate 506. This massage airbag is located between the two first massage airbags 507 and massages the bottom of the forearm or hand, forming a U-shaped massage airbag assembly to improve comfort. The second mounting plate 205 can also have a massage airbag added between the two second massage airbags 206, forming a U-shaped massage airbag assembly.

[0033] A fixing plate 9 is provided between the two supporting legs 2. The bottom of the fixing plate 9 is flush with the bottom of the supporting legs 2. The fixing plate 9 has a cavity 901 that communicates with the outside. An electric push rod 902 is fixed to the side wall of the cavity 901. A foot pedal 6 is fixed to the telescopic end of the electric push rod 902. Two second electrode plate assemblies 601 are installed on the foot pedal 6. The fixing plate 9 and the electric push rod 902 facilitate the storage of the foot pedal 6. When the foot pedal 6 is needed, the electric push rod 902 is controlled by the control system to push the foot pedal 6 out of the fixing plate 9.

[0034] An air pump is installed on the top of the fixed plate 9. The air pump is connected to the first massage airbag 507 and the second massage airbag 206 through pipes.

[0035] When a user needs a massage, if they require a forearm or hand massage, they open the support plate 508 and activate the electric telescopic rod 505 via the APP to extend it. After the first massage airbag 507 rises to a suitable position, the user selects the massage mode and intensity. The first massage airbag 507 inflates and uses the massage protrusions 7 to perform the massage. If they require a leg massage, they open the sealing plate 207 and control the electric slider 204 to move via the APP, which moves the second mounting plate 205 to bring the second massage airbag 206 closer to the leg. Similarly, they select the massage mode and intensity to perform the massage.

[0036] The smart chair provided by this invention integrates multiple sensors in its components to measure heart rate, body temperature, blood pressure, weight, and body composition, as well as provide reminders for prolonged sitting and poor posture. The armrests and support legs are equipped with retractable massage components, providing massage services to users through first and second massage airbags. It can also connect to mobile terminal devices and has a companion app, offering users comprehensive health monitoring, posture management, and a comfortable experience.
