Our spine protection backrest is heatedmolded by a hairdryer (80°C), which is lightbreathable,fits the body. Wearing this colorful backrest is as exciting as wearing a fashionable jacket. Our products overcome all the shortcomings of traditional metal brackets, such as bulky, airtight, unfit, clumsy appearance, etc. This composite material can be completely recycled to meet the requirements of green products. The weather resistance of this material is compared with the world＇s competitor Allard＇s composite material,the service life of our material is increased by 2.5 times.

We develop smart fabrics by electrospinning crystallinity-modified self-healing materials, which are facilitated by the reversible physical crosslinking between poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)ionic liquid. The fiber morphology can be maintained without losing the fibrous structure. The fabrics can achieve the healing effects without the need of seamingany adhesive. The fabrics are waterproofbreathable. By printing electrically conductive channels using ionic liquid, capacitive pressure sensorsresistive tensile sensor arrays are fabricated.
