Scientists create smart bandage that heals wounds faster using electrical stimulation and sensors

Scientists have created a “smart” patch that uses electrical currents to heal wounds 25 percent faster than traditional methods by stimulating tissues to speed up recovery.

The smart bandage consists of a wireless circuit that uses the flow of electrical currents and temperature sensors to monitor the wound healing process.

high tech device According to the researchers, it promotes faster wound closure, increases blood flow to damaged tissues, and speeds up skin repair by significantly reducing scarring.

The wireless high-tech headband is the work of Stanford University researchers and was described in a paper published November 24 in natural biotechnology.

Scientists have developed a smart dressing that can help speed up wound healing by observing the injury and treating it at the same time.

The smart dressing consists of a wireless circuit (see above) that uses the flow of electrical currents and temperature sensors to control the wound healing process.

When a person’s wound has not yet healed or the dressing detects an infection, the sensors can apply stronger electrical stimulation to the wound area to speed up tissue repair and reduce the risk of infection.

Smart dressing biosensors can monitor biophysical changes in the environment and provide a fast and highly accurate way to measure the condition of a wound in real time.

The researchers were able to track sensor data in real time on a smartphone wirelessly.

“In mice, we demonstrate that our wound care system can constantly monitor skin impedance and temperature and provide electrical stimulation in response to the wound environment,” the researchers study abstract states.

In preclinical mouse wound models, the treatment group healed approximately 25% faster than the control group.

“The smart dressing protects the wound while it heals,” Yuanwen Jiang, study co-author and doctoral student at the Stanford School of Engineering, said in a statement.

“But it is not a passive instrument. This is an active healing device that could change the standard of care for chronic wounds.”

The scientists wanted to determine why and how electrical stimulation promotes wound healing.

They now believe that electrical stimulation promotes the activation of pro-regenerative genes such as Selenop, an anti-inflammatory gene found to help in killing pathogens and healing wounds, and Apoe, which has been shown to increase muscle and soft tissue. tissue growth.

In addition, electrical stimulation increased the number of leukocyte populations, especially monocytes and macrophages, which may also play a role in certain phases of wound healing.

“With stimulation and sensors in one device, the smart dressing speeds up healing, but also tracks how the wound is improving,” Artem Trotsyuk, also co-author of the study, and currently head of the Department of Surgery and professor. biomedical engineering at the University of Arizona at Tucson.

These hurdles include increasing device size to human scale, reducing costs, and solving long-term data retention issues.

All this will need to be resolved before moving on to mass production.

They also noted other potential sensors that could be added to the device, including those that measure metabolites and other biomarkers.

One potential hurdle for clinical use could be “hydrogel rejection”, where a person’s skin can react to the device and create a poor combination of gel and skin.
