Scientists from US have developed a smart bandage that can precisely control dose and delivery schedule of medication tailored for a specific type of wound, leading to faster healing.
This is the first bandage that is capable of dose-dependent drug release and can be used to heal chronic wounds or battlefield injuries. Moreover, this platform can be applied to many different areas of biomedical engineering and medicine.
The smart bandage consists of electrically conductive fibres coated in a gel that can be individually loaded with infection-fighting antibiotics, painkillers, tissue-regenerating growth factors or other medications. It has microcontroller having size of postage stamp, which can be triggered by smartphone or other wireless device. When it is triggered, microcontroller sends small amounts of voltage through a chosen fibre which heats fibre and its hydrogel, releasing whatever cargo it contains.
