A team of scientists has been working on the prototype of a smart bandage that, with some help from its smartphone controls, might help chronic wounds heal faster. It would do so thanks to its medically coated fibers.
The Smart Bandage and What its Made of
This smart bandage prototype is about the size of a postage stamp. It includes electrically conductive fibers which are coated in a gel that can deliver specific medications, for example, antibiotics. It could also carry painkiller, or tissue-regenerating growth factors, among others.
The prototype and probably the end product as well as being controlled by a wireless device, for example, a smartphone. This can send voltage to one of the bandage’s particular fibers. Then, it hits its gel, which then releases the medicine or painkiller over the wounded area.
University of Nebraska-Lincoln scientists are the developers of this smart bandage prototype. According to them, their invention could, at least initially, be used in treating chronic skin wounds caused by diabetes.
The research team also states that their creation might help deliver more than one medication through a single bandage. It would also be able to offer an exact control over the drug and its delivery schedule. This way, the bandage is also very adaptable and would function based on the type of wound.
“This is the first bandage that is capable of dose-dependent drug release. You can release multiple drugs with different release profiles. That’s a big advantage in comparison with other systems.”
This is according to Ali Tamayol, a University of Nebraska assistant professor of mechanical and materials engineering.
The team points out that its invention is still in prototype mode and that it will take years before it becomes available on the market.
Before it does so, it will also need to pass through animal and human trials. Detailed study findings of the current results are available in the journal Advanced Functional Materials.
