Our system uses wireless insole in the shoes to measure foot plantar pressure of athletes.

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.

　　This pressure-detection smart baseball obtains applied force, dynamicinertial features of pitcher during pitching. Through the connection between wireless moduleterminal, data will be transferredprovides vibration as a pitching signal. Also, precise adjustment is achievable through back-end analysiscustomized training formulation, which enhances pitching ability, optimizes training,improves pitcher＇s condition assessment.
