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.

A wearable sweat sensing device is developed for health monitoring during exercises to prevent illness caused by fluid losses. By biomimetic designchoosing material with high permeability, the sweat collector possesses high sweat collection efficiency, rapid transportlow response time. Inside the channel, salt concentrationsweat rate is deduced by electric property analysis. Finally
