创可贴是每家每户的常备药品之一,但有时这个便利的伤口处理品也经常会让人烦心。如伤口位置特殊,很难贴合;遇水变得一团糟等。来自美国麻省理工学院的科学家们发明了一种新材料,让创可贴有了更大的用武之地。这种凝胶状材料可以随意拉伸、弹性较高,可以更好地贴合在任何部位。用其制成的创可贴,包含半导体芯片、LED灯以及药物输送系统。创可贴会根据体温变化,选择并释放特定药物。当创可贴内含药量不足时,还会通过LED灯给予提示。 Band-Aid is one of the staple medicines for every household, but sometimes this convenient wound treatment is often annoying. If the wound position is special, it is difficult to fit; water becomes a mess and so on. Scientists from the Massachusetts Institute of Technology invented a new material that made the Band-Aid even more useful. This gel-like material can be freely stretched, high elasticity, can better fit in any part. Band-Aid made of it, including semiconductor chips, LED lamps, and drug delivery systems. Band-Aid will choose and release a specific medication based on changes in body temperature. When the Band-Aid contains less than the amount of medicine, but also through the LED lights to give tips.
