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

by admin

Scientists have created a smart “band-aid” that uses electrical current to heal wounds 25% faster than traditional methods by stimulating tissue to speed healing.

The smart bandage consists of a wireless circuit that uses current flow and temperature sensors to monitor wound healing progress.

According to researchers, the high-tech device promotes faster wound closure, increases new blood flow to damaged tissue, and accelerates skin healing by significantly reducing scar formation.

The wireless high-tech bandage is the work of researchers at Stanford University and was featured in a paper published Nov. 24. nature biotechnology.

If a person’s wound has not yet healed, or if the bandage detects an infection, the sensor applies electrical stimulation across the wound area to help speed tissue healing and reduce infection.

Biosensors in smart dressings can track biophysical changes in the local environment and provide a real-time, fast and highly accurate method for measuring wound status.

Researchers were able to track sensor data in real time with their smartphones, without the need for wires.

“In mice, we show that the wound care system can continuously monitor skin impedance and temperature and deliver electrical stimulation in response to the wound environment,” said the researchers’ abstract of the study.

In a preclinical wound model in mice, the treatment group healed approximately 25% faster than the control group.

“When closing a wound, the smart bandage protects the wound as it heals,” said Yuanwen Jiang, a co-lead author of the study and a postdoctoral fellow in Stanford University’s School of Engineering, in a statement.

But it is not a passive tool. This is an active healing device that has the potential to change the standard of care in treating chronic wounds. ”

Scientists wanted to determine why and how electrical stimulation accelerates wound healing.

They now show that electrical stimulation activates pro-regenerative genes such as Selenop, an anti-inflammatory gene that has been shown to aid in pathogen clearance and wound repair, and Apoe, which has been shown to increase muscle and flexibility. believe to promote organizational growth.

In addition, electrical stimulation increases the amount of leukocyte populations, especially monocytes and macrophages, and can also play a role in certain stages of wound healing.

“By stimulating and sensing in one device, the smart bandage accelerates healing but also tracks wound healing,” said Artem, co-first author of the study and now professor of surgery. Trotsyuk said. explained a doctor of biomedical engineering at the University of Arizona in Tucson.

Scientists also warn that smart bandages are currently a proof-of-concept and have some challenges.

These hurdles include scaling device sizes to human scale, reducing costs, and solving long-term data storage problems.

All of this needs to be addressed before scaling up to mass production.

They also mentioned other sensors that could potentially be added to the device, such as sensors that measure metabolites and other biomarkers.

One potential obstacle to clinical use is ‘hydrogel rejection’. This can cause a person’s skin to react to the device, resulting in a bad combination of gel and skin.
