The breathing rate is obtained through subsequent conversion and calculation.

[0086] In one embodiment of the present invention, such as Figure 12 As shown, the first breathing sensor 31 and the second breathing sensor 32 are Bernoulli pressure sensors.

The first bending portion 211 can be bent upwards along the second bending line 42 toward the first surface of the substrate body. There is a third bending line 43 between the third bending portion 221 and the fourth bending portion 222. The third bending portion 221 can be bent upwards along the third bending line 43 toward the first surface of the substrate body, such that the first breathing sensor 31 located in the first bending portion 211 and the second breathing sensor 32 located in the third bending portion 221 are arranged in parallel, and the first breathing sensor 31 and the second breathing sensor 32 are at the same distance from the substrate body 100.

The folding arm unit and the baffle unit have corresponding breathing airways 400, that is, the breathing airway 400 is located in the area between the first baffle 301 and the second baffle 302. The first breathing sensor 31 and the second breathing sensor 32 are located on both sides of the breathing airway 400. The airflow exhaled from the nostrils acts on the first breathing sensor 31 on the first bending portion 211 and the second breathing sensor 32 on the third bending portion 221 along the breathing airway 400. The first breathing sensor 31 and the second breathing sensor 32 sense the pressure change generated by the breathing airflow and generate a corresponding resistance value. The breathing rate is obtained through subsequent conversion and calculation.

[0088] By using the arrangement of the first and second respiratory sensors, the pressure changes of the respiratory airflow are detected, enabling the detection of respiratory frequency and depth. This method has the advantages of high sensitivity, fast response speed, simple structure, and miniaturization, and can be widely used in fields such as medical diagnosis, ventilator monitoring, and sports and health monitoring.

[0089] In this embodiment of the invention, the breathing detection structure further includes an adhesive layer located on the second surface of the substrate body 100.

[0090] In this embodiment of the invention, the adhesive layer is a double-sided bio-gel, wherein one side of the double-sided bio-gel is bonded to the second surface of the substrate, and the other side of the double-sided bio-gel is bonded to the human body surface.

[0091] The double-sided biogel has good flexibility and mechanical strength, and can withstand certain deformations without breaking, thus maintaining the flexibility of the respiratory detection structure.

[0092] In other embodiments, the adhesive layer may be made of other suitable materials depending on the application.

[0093] The present invention also provides a respiratory detection system, including the respiratory detection structure described above.

[0094] In this embodiment of the invention, the breathing detection structure further includes a detection chip, which obtains the corresponding breathing frequency and depth based on the pressure changes of the breathing airflow detected by the first breathing sensor and the second breathing sensor, thereby realizing breathing detection.

[0095] In this embodiment of the invention, the detection chip is located within the substrate body 100.

[0096] In other embodiments, the detection chip and the respiration detection structure are packaged separately and electrically connected by metal wires or other suitable means.

[0097] When using the respiratory detection system provided by this invention for respiratory detection, the system is attached to the skin below the nostrils. Breathing airflow passes through the respiratory duct of the system. The first and second respiratory sensors detect changes in the pressure of the breathing airflow for respiratory detection. The system is small, lightweight, and comfortable to wear, suitable for prolonged use by adults, the elderly, and children. The layout design of the first and second respiratory sensors enables high accuracy in detecting breathing based on changes in air pressure corresponding to the breathing airflow. Real-time breathing airflow rate data is then transmitted to a mobile terminal for monitoring, and abnormal data alarms are triggered, allowing for timely detection and handling of abnormal breathing phenomena.

[0098] This invention also provides a respiratory detection circuit based on the respiratory detection structure, such as... Figure 13 As shown, it includes: two sets of airflow sensing units and two operational amplifiers; each set of airflow sensing units is connected to one operational amplifier.

[0099] Each airflow sensing unit includes a first breathing sensor 31, a second breathing sensor 32, a first upper resistor RU1, and a first lower resistor RD1. One end of the first breathing sensor 31 is connected to one end of the first lower resistor RD1, and the other end of the first lower resistor RD1 is connected to one end of the second breathing sensor 32 and grounded. The other end of the second breathing sensor 32 is connected to one end of the first upper resistor RU1, and the other end of the first upper resistor RU1 is connected to the other end of the first breathing sensor 31, serving as the input terminal of the airflow sensing unit. The positive input terminal of the operational amplifier is connected to one end of the first breathing sensor 31 and one end of the first lower resistor RD1, and the negative input terminal of the operational amplifier is connected to the other end of the second breathing sensor 32 and one end of the first upper resistor RU1. The output terminal of the operational amplifier outputs a detection signal.

[0100] When the airflow passes through the breathing detection circuit, the breathing detection circuit ultimately outputs the detection voltage signal of the airflow sensing unit.

[0101] The breathing detection circuit described above detects breathing by measuring changes in airflow. Furthermore, the first and second breathing sensors convert breathing pressure values ​​into pressure values, and by using the relationship between air pressure and wind speed conversion coefficients, the airflow magnitude can be calculated, thus enabling breathing detection.

[0102] Finally, it should be noted that any modification or equivalent substitution of some or all of the technical features based on the device structure and the technical solutions of the embodiments of the present invention, without departing from the corresponding technical solutions of the present invention, shall fall within the patent scope of the device structure and the embodiments of the present invention.
