Bandage technology has gradually been revolutionised in the 100 years since Band-Aids were first introduced. Researchers from the University of Nebraska-Lincoln, Harvard Medical School and MIT are now ready to introduce the next century of wound care with the “smart bandage”.
The smart bandage has individual fibres that store medications which can be later implemented using a smartphone or another mobile device. The bandage is made up of electrically conductive fibres that are coated in a gel that can house medications. Antibiotics and painkillers can be used within the bandage, and possibly many other effective combinations that will enhance recovery.
Individual fibres can then be activated via voltage from a connected micro-controller no larger than a post stamp using a connected mobile device. Ali Tamayol, Assistant Professor of Mechanical & Materials Engineering at Nebraska, explained: “This is the first bandage that is capable of dose-dependent drug release, you can release multiple drugs with different release profiles.”
This is an exciting platform that can potentially be applied to many different areas of biomedical engineering and medicine. Not only could it be useful for dealing with battlefield injuries, it could also help in the treatment of chronic wounds, which are common in patients living with diabetes.
This is not the only “next gen” bandage in development. A team from Swansea University’s Institute of Life Science has created bandages laden with nano-scale sensors that can instantaneously transmit health information to medical professionals using 5G wireless data.
