有生命的创可贴 / The Intelligent Band-Aid

有生命的创可贴

In everyday life we often do not know when to replace the used band-aid. According to this problem, we have found that it can be solved by testing the pH levels in the body for the improvement of the band-aid, because the health skin and healing wound normally have pH values below 5. Once the bacterial infection or disease complications increase, the wound will turn from acidity to alkaline, and pH value may increase to 6.5-8.5, and the indicator color of the band-aid will turn to red from colourless. The red smiley face on it which shows the end of life of a marked band-aid.
