Now, researchers at Stanford University have created a smart band-aid that uses electrical currents to heal wounds 25 percent faster than traditional methods by stimulating tissue to speed up the recovery process. The researchers say in a published <a href="https://www.nature.com/articles/s41587-022-01528-3">paper</a> that their smart band-aid promotes faster closure of wounds, increases the blood flow to injured tissue, and enhances skin recovery by stimulating electric current to the wound. <cmsannotation type="cmsannotation" annotationid="Combating infection with electrical stimulation" comment="subhead" text="Combating infection with electrical stimulation">Combating infection with electrical stimulation</cmsannotation> Electrical stimulation, also known as galvanotaxis, has been previously reported to accelerate the migration of keratinocytes to the wound site, which limits bacterial infection and actively promotes tissue growth, and contributes to tissue repair. <div type="image" title="‘Smart’ bandage" msid="97274260" hostid="261"></div> This smart bandage comprises of electronic layer, including a microcontroller unit, electrical stimulator, memory, radio antenna, biosensors, and other components. It is just 100 microns thick. All these components are cleverly engineered in hydrogel - a rubber and skin-like polymer. All the components are integrated to deliver electrical stimulation to the wound and collect real-time biosensor data, such as skin temperature and biophysical changes. It allows researchers to track the data in real time on a smartphone without the need for wires. When the bandage is applied to the wound, it detects the infection, and sensors in the smart bandage deliver electrical stimulation across the wound area to speed up tissue recovery and lower the infection. Bandage’s biosensing capabilities monitor biophysical changes and sense temperature changes in the skin as the wound heals. “With stimulation and sensing in one device, the smart bandage speeds healing, but it also keeps track as the wound is improving,” says Artem Trotsyuk, a co-first author of the study. <cmsannotation type="cmsannotation" annotationid="Positive results and new directions" comment="subhead" text="Positive results and new directions">Positive results and new directions</cmsannotation> The researchers said, “In mice, we demonstrate that our wound care system can continuously monitor skin impedance and temperature and deliver electrical stimulation in response to the wound environment.” In preclinical wound models with mice, the wound healed about 25% faster than the traditional method. Researchers now believe electrical stimulation heals wounds faster, and it also promotes the activation of pro-regenerative genes like ‘Selenop,’ an anti-inflammatory gene that contributes to wound repair, and ‘Apoe,’ which has been shown to increase muscle and soft tissue growth. Scientists also found that electrical stimulation increases the white blood cell population, namely macrophages and monocytes. Researchers at Stanford University caution that the smart bandage is, as yet, a proof of concept but a promising one. According to them, many challenges remain; these include the size of the device to human scale, solving long-term data storage, reducing cost, and scaling up to mass production. Despite these hurdles, the researchers are pushing ahead and are optimistic about the potential of smart bandages.

This smart bandage senses and treats bacterial infections 25% faster

US researchers have developed a novel smart bandage with <keyword id="301435" type="General" weightage="20" keywordseo="biosensors" source="Orion">biosensors</keyword> that can help heal chronic wounds like diabetic ulcers and burns. Most of the time, when someone gets a cut, scrape, burn or other wounds, the body takes care of itself and heals on its own. But <keyword id="6359018" type="General" weightage="20" keywordseo="diabetes" source="Orion">diabetes</keyword> can interfere with the healing process and create wounds that will not go away and that could become infected and fester. The smart bandage developed by researchers at the California Institute of Technology (<keyword id="140396" type="General" weightage="20" keywordseo="caltech" source="Orion">Caltech</keyword>) may make treatment of these wounds easier, more effective and less expensive. "There are many different types of chronic wounds, especially in diabetic ulcers and burns that last a long time and cause huge issues for the patient," Wei Gao, Assistant Professor of medical engineering, at Caltech said. "There is a demand for technology that can facilitate recovery," Gao said. Unlike a typical bandage, which might only consist of layers of absorbent material, <keyword id="1228303" type="General" weightage="20" keywordseo="smart-bandages" source="Orion">smart bandages</keyword> are made from a flexible and stretchy polymer containing embedded electronics and medication. The electronics allow the sensor to monitor for molecules like uric acid or lactate and conditions like pH level or temperature in the wound that may be indicative of inflammation or bacterial infection. The bandage can transmit the gathered data from the wound wirelessly to a nearby computer, tablet, or smartphone for review by the patient or a medical professional. It can deliver an antibiotic or other medication stored within the bandage directly to the wound site to treat the inflammation and infection. It can also apply a low-level electrical field to the wound to stimulate tissue growth resulting in faster healing, the researchers said, in the paper described in the journal Science Advances. The team tested the bandage in animal models under laboratory conditions. The smart bandages showed the ability to provide real-time updates about wound conditions and the animals' metabolic states to researchers, as well as offer speed healing of chronic infected wounds similar to those found in humans Gao said the results are promising, adding that future research will focus on improving the bandage technology and testing it on human patients.
