Recently, the Australian research team has invented an intelligence that can show the degree of wound healing through color change. bandage 。 It is reported that this liquid crystal is made of. fibre It can be generated according to the change of wound temperature. colour The change from red to blue. Bandaging the wound with this fibrous bandage can significantly enhance wound healing for recurrent infections and early inflammation. If infected, the wound usually warms up. If the blood supply is normal, the temperature of the wound will drop. This bandage can effectively save doctors' time and money for trauma treatment, mainly for chronic wounds, for those who are very slow in wound healing, obesity and diabetes.
