A new type of bandage combines wireless electrical stimulation and biosensors to bring hope to patients with slow-to-heal injuries.
Some wounds just won’t heal. Infections, diseases like diabetes, and suppressed immune systems often stack up to slow healing. Chronic wounds can last months and lead to anxiety and depression. In the worst cases, they are life threatening. Cost of treatment has soared to $25 billion each year.
So far, however, solutions for treating chronic wounds have been few and far between, but researchers at Stanford University now report that they have developed a wireless smart bandage that has shown promise in speeding up tissue repair by monitoring the wound healing process and treating the wound simultaneously. The researchers say in a paper published November 24th in Nature Biotechnology that their device promotes faster closure of wounds, increases new blood flow to injured tissue, and enhances skin recovery by significantly reducing scar formation.
