For faster healing, try smart bandage. According to a new research, studies have found that smart bandage could expedite healing.Researchers have designed a smart bandage that could eventually heal chronic wounds or battlefield injuries with every fiber of its being; the study was conducted by the University of Nebraska-Lincoln, Harvard Medical School and MIT.
The bandage consists of electrically conductive fibres coated in a gel that can be individually loaded with infection-fighting antibiotics, tissue-regenerating growth factors, painkillers or other medications.
A microcontroller no larger than a postage stamp, which could be triggered by a smartphone or other wireless device, sends small amounts of voltage through a chosen fibre. That voltage heats the fibre and its hydrogel, releasing whatever cargo it contains.
A single bandage could accommodate multiple medications tailored to a specific type of wound, the researchers said, while offering the ability to precisely control the dose and delivery schedule of those medications. The combination of customization and control could substantially improve or accelerate the healing process, said Ali Tamayol, assistant professor of mechanical and materials engineering at Nebraska.Though the researchers have patented their design, it will need to undergo further animal and then human testing before going to market. That could take several years, though the fact that most of the design’s components are already approved by the Food and Drug Administration should streamline the process, Tamayol said.
In the meantime, he said, the researchers are also working to incorporate thread-based sensors that can measure glucose, pH and other health-related indicators of skin tissue.
Integrating that capability would allow the team to create a bandage that could autonomously deliver proper treatments.
