Scientists create smart BANDAGE that can heal wounds faster with electrical stimulation and sensors

Scientists have created a clever ‘band-aid’ that uses electrical currents to heal wounds 25 percent faster than traditional methods by stimulating tissue to accelerate healing.

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

According to the researchers, the high-tech device allows wounds to close faster, increases new blood flow to injured tissue, and improves skin healing by significantly reducing scar formation.

The wireless, hi-tech bandage is the work of Stanford University researchers and is featured in a paper published Nov. 24. Nature Biotechnology.

When a person’s wound is not yet healed or the bandage detects an infection, the sensors can apply further electrical stimulation across the wound site to help speed tissue healing and reduce infection.

The smart bandage’s biosensors can monitor biophysical changes in the local environment and provide a real-time, fast and highly accurate way to measure wound status.

The researchers were able to track the sensor data in real time on a smartphone without the need for cables.

«We demonstrated in mice that our wound care system can continuously monitor skin impedance and temperature and provide electrical stimulation in response to the wound environment,» the researchers wrote.

In preclinical wound models with mice, the treatment group healed approximately 25% faster compared to the control group.

«The smart bandage protects the wound as it heals,» said Yuanwen Jiang, a postdoctoral fellow at the Stanford School of Engineering and co-author of the study.

But it is not a passive tool. It is an active healing device that can change the standard of care in the treatment of 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 aid pathogen clearance and wound repair, and Apoe, which has been shown to increase muscle and softness. tissue growth.

In addition, electrical stimulation increased the amount of white blood cell populations, particularly monocytes and macrophages, which may also play a role in certain stages of wound healing.

Similarly, one of the study’s co-authors and now Head of Surgery and Professor Artem Trotsyuk said, «With stimulation and sensing in one device, the smart bandage accelerates healing, but also tracks the healing process of the wound.» from the Department of Biomedical Engineering at the University of Arizona at Tucson.

The scientists also warned that the smart bandage is currently a proof-of-concept and poses some challenges.

These hurdles include scaling up the device to human scale, reducing cost, and solving long-term data storage issues.

All of this had to be addressed before it could go into mass production.

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

A potential barrier to clinical use would be ‘hydrogel rejection’; in this case, a person’s skin may react to the device and create a bad gel-skin combination.

The researchers also pointed out other potential sensors that could be added to the device, including those that measure metabolites and other biomarkers.
