Most importantly , the disposed hydrogel could be gathered into transparent , whippy , self-adhesive , self-healing and high sensitive strain/pressure detector for monitoring human body movement . This work may pave the way for inventing the multifunctional chitosan-based hydrogels which has potential diligence in the bailiwicks of wearable sensor and soft electronic devices.Tannic acid-loaded chitosan-RGD-alginate scaffolds for injury healing and skin regeneration.Hydrogels have drawn much care in
