Problems solved by technology

[0005] However, for high-performance flexible sensors, in addition to achieving high response and sensitivity in one device, they should also meet the core technical requirements of future wearable sensors—biocompatibility, which poses great challenges to material and device design. At the same time, the high price of raw materials (Pt, Au, etc.) required in the assembly stage also limits the development of flexible sensors

Embodiment 1

[0031] (1) The preparation process of MXene:

[0032] The etching solution of LiF, hydrochloric acid and ultrapure water with a mass ratio of 1.5:18.3924:5 was fully stirred, and 1gMAX phase (Ti 3 AlC 2 ) Powder, continue to stir for 24h until the etching is complete. Centrifuge at 3500r / min for several times to wash until the pH of the supernatant is close to 7. Then, the obtained precipitate was fully dispersed in deionized water, and the upper black liquid was collected by centrifugation at 3500 r / min for 5 minutes, which was the MXene dispersion. figure 1 Based on the XRD pattern of MXene prepared in Example 1, it can be seen that MXene is completely etched.

[0033] (2) MXene / fabric adsorption treatment:

[0034] Put a certain size of pure cotton cloth into the petri dish containing the MXene\water dispersion obtained in step (1), take it out and dry it in cold air after it is fully immersed, such as figure 2 Shown. Combine image 3 with Figure 4 , It can be seen that the p...

Embodiment 2

[0039] (1) The preparation process of MXene:

[0040] The etching solution of LiF, hydrochloric acid and ultrapure water with a mass ratio of 1.0:15.0312:5 was fully stirred, and 1gMAX phase (Ti 3 AlC 2 ) Powder, continue to stir for 25h until the etching is complete. Centrifuge at 3600r / min for several times to wash until the pH of the supernatant is close to 7. Then, the obtained precipitate was fully dispersed in deionized water, and the upper black liquid was collected by centrifugation at 3600r / min for 6min, which was the MXene dispersion.

[0041] (2) MXene / fabric adsorption treatment:

[0042] Put a certain size of cupra into a petri dish containing the MXene\water dispersion obtained in step (1), take it out after immersion and dry it with cold air, such as figure 2 Shown. Combine image 3 with Figure 4 It can be seen that the cupro ammonia cloth has a large amount of adsorption to MXene, good adhesion, and it is not easy to fall off after washing for a long time, and the...

Embodiment 3

[0047] (1) The preparation process of MXene:

[0048] The etching solution of LiF, hydrochloric acid and ultrapure water with a mass ratio of 1.25:21.6936:5 was fully stirred, and 1gMAX phase (Ti 3 AlC 2 ) Powder, continue to stir for 26h until the etching is complete. Centrifuge at 3700r / min for several times for washing until the pH of the supernatant is close to 7. Then, the obtained precipitate was fully dispersed in deionized water, and the upper black liquid was collected by centrifugation at 3700 r / min for 7 minutes, which was the MXene dispersion.

[0049] (2) MXene / fabric adsorption treatment:

[0050] Put a certain size of non-woven fabric into the petri dish containing the MXene\water dispersion obtained in step (1), take it out after being fully immersed and dry it with cold air, such as figure 2 Shown. Combine image 3 with Figure 4 It can be seen that the non-woven fabric has a large amount of MXene adsorption, good adhesion, and it is not easy to fall off after a l...

Description

Technical field [0001] The invention belongs to the field of force sensitive sensors, and particularly relates to an MXene coated textile force sensitive sensor and a preparation method thereof. Background technique [0002] With the emergence of smart wearable electronic products, sensor devices can play a key role in the detection of humans and their surrounding environment. The flexible sensor device has easy processing, low cost, light weight, and excellent impact resistance and durability, providing new possibilities for creating smart wearable systems. It has become essential in many application fields such as medical diagnosis, sports monitoring and human-machine interface. A flexible sensor device is a functional material that can be attached to the surface of various irregular objects and can sense the forces on the surface of the material (compression, bending, stretching, twisting, etc.). [0003] Traditional wearable equipment is a complete sensing device that combine...
