The ethanol sponge uses a polyurethane sponge as an elastic substrate, and a conductive solvent coating is applied on the ethanol sponge as a conductive sensing layer. After standing still, conductive sponge 1 is obtained. When in use, first immerse the polyurethane sponge in ethanol for ultrasonic cleaning; then put it into a vacuum drying oven and dry it at a temperature of 60°C for 2 hours; then apply the prepared conductive solvent on the dried ethanol sponge and squeeze the ethanol sponge to remove the excess conductive solvent; let the coated ethanol sponge stand still at a temperature of 25°C and a humidity of 50% for 8 hours to obtain conductive sponge 1.

[0020] In this embodiment, conductive silver paste 2 is applied on the upper and lower surfaces of the conductive sponge 1, and copper cloth 3 is fixed on the upper and lower surfaces of the conductive silver paste 2. It further includes a paraffin film for encapsulating the conductive sponge 1 and the copper cloth 3 to insulate the conductive sponge 1 from the outside; secondly, the conductive sponge flexible sensor is prepared using the above-mentioned conductive sponge 1. Apply conductive silver paste 2 on the upper and lower surfaces of the conductive sponge 1, then cover the copper cloth 3 on the upper and lower surfaces, and finally, encapsulate it with a paraffin film to obtain the conductive sponge flexible sensor.

[0021] In this embodiment, the copper cloth 3 is a flexible conductive silver-plated tape; it has good flexibility, ductility, can be freely bent or even folded.

[0022] In this embodiment, the conductive sponge 1 includes a sandwich structure, a cross structure, and a vertical structure; by changing the structure of the conductive sponge flexible sensor, the sensitivity of the conductive sponge flexible sensor can be changed. Among them, the vertical structure and the sandwich structure have higher sensitivities, around 0.3N - 1. The "cross" structure has the widest measurement range, reaching 0.75 - 4N. Different structures of the conductive sponge 1 have different sensitivities, and in actual use, it can be determined according to the actual situation.

[0023] In this embodiment, it further includes a wearing component 4 for wearing the conductive sponge flexible sensor on different parts of the human body. The conductive sponge flexible sensor can be built into the inner side of the wearing component 4; the wearing component 4 is a double-layer hollow structure, with an interlayer 401 provided in the middle. An air extraction component for extracting the air in the interlayer 401 to make the wearing component 4 fit more closely to the human body part is provided on the outer side of the wearing component 4; by setting the wearing component 4, wristbands and ankle bands with built-in conductive sponge flexible sensors are worn on multiple parts of the human body. When pressure is generated on the conductive sponge flexible sensor due to human movement, the sponge skeleton of the conductive sponge 1 will change, thereby causing the conductive characteristics of the conductive sponge 1 to change. Different values of the resistance of the conductive sponge sensor are obtained through different pressures generated during the human movement process, realizing the monitoring of the human movement state.

[0024] In this embodiment, the air extraction component includes a micro air pump 5, a pressure sensor 7, and a microcontroller 6. The micro air pump 5 and the microcontroller 6 are arranged on the outside of the wearable component 4, and the air extraction port of the micro air pump 5 is connected to the interlayer 401. The pressure sensor 7 is arranged on the inside of the wearable component 4 and contacts the human body part; the pressure sensor 7 monitors the wearing effect of the wristband, ankle strap, etc. at all times. If the wearing is loose, the human body motion state monitoring data of the conductive sponge flexible sensor is abnormal, and the micro air pump 5 will be controlled to operate to evacuate the air in the interlayer 401 of the wearable component 4, so that the wearable component 4 shrinks and is worn more closely on multiple parts of the human body to ensure the accuracy of human body motion state monitoring.

[0025] In this embodiment, an alarm component is also included, which includes an alarm light 8. The alarm light 8 is set on the outside of the wearable component 4 and is connected to the output end of the microcontroller 6; the pressure sensor 7 monitors the wearing effect of the wristband, ankle strap, etc. at all times. If the wearing is loose, an abnormal pressure signal is generated and transmitted to the microcontroller 6. Through the signal conversion of the microcontroller 6, the alarm light 8 is controlled to sound an alarm to remind the monitoring personnel to take action.

[0026] In this embodiment, the wearable component 4 includes a wristband and an ankle strap. The wristband and ankle strap are elastic, making it convenient to wear the conductive sponge flexible sensor on various parts of the human body.

[0027] In this embodiment, the control circuit of the present invention is a common circuit in the circuit field, and can be implemented by those skilled in the art, so it will not be described in detail here.

When the human body movement generates pressure on the conductive sponge flexible sensor, the sponge bone of the conductive sponge 1 The frame will change, thereby causing the conductive properties of the conductive sponge 1 to change. Through the different pressures generated during human movement, different values ​​of the resistance of the conductive sponge flexible sensor are obtained, thereby realizing the monitoring of the human body's movement state; the pressure sensor 7 monitors the wearing effect of the wristband, ankle strap, etc. at all times. If the wearing is loose, the human body movement state monitoring data of the conductive sponge flexible sensor is abnormal, and the micro air pump 5 will be regulated to operate, and the air in the interlayer 401 of the wearable component 4 will be evacuated, so that the wearable component 4 will shrink and be worn more tightly on multiple parts of the human body, thereby ensuring the accuracy of human body movement state monitoring; the force sensor monitors the wearing effect of the wristband, ankle strap, etc. at all times. If the wearing is loose, a pressure abnormality signal is generated and transmitted to the microcontroller 6. Through the signal conversion of the microcontroller 6, the alarm light 8 is regulated to sound, reminding the monitoring personnel to handle it.
