Wireless Electric Dressing Accelerates Chronic Wound Healing

A research team from Stanford University in the USA decided to investigate a problem that affects millions of people around the world: chronic wounds, an underrecognized medical concern that deals with delayed healing in patients with infections, diabetes, weakened immune systems, among other conditions.

To speed up the healing of these woundsWith the treatment cost exceeding US$25 billion in the United States alone, researchers have developed a smart dressing consisting of a flexible and wireless bioelectronic system (like a wearable) combined with human-interface hydrogel electrodes with feedback control sensors and stimulation circuits. skin.

How does the smart bandage work?

The principle of the new treatment: “Smart dressing heals while protecting the wound by closing it”explains EurekAlert Yuanwen Jiang, a postdoctoral fellow at the Stanford School of Engineering, is also a co-author of the study.

Therefore, it is not a passive tool. “This is an active healing device that could change the standard of care for treating chronic wounds,” says the pharmacist. Smart dressing detects conductivity and temperature changes in the skin as the wound heals (impedance increases and local temperature decreases🇧🇷

According to the authors, the “magic” happens because electrical stimulation activates the anti-inflammatory gene. selenope this supportIncreases muscle and soft tissue growth. In rat preclinical wound models, treatment group heals approximately 25% faster and with 50% improvement in dermal remodeling compared to the control group.

The results of the research were published in the scientific journal Nature Biotechnology🇧🇷
