Smart bandages for wound healing

 Smart bandages for wound healing. Many of us do not want to heal easily when a wound occurs in the body. There is also fear of infection if the wound is bandaged. For this reason, doctors recommend the use of sterilized bandages. Once the bandage is applied, the extent of the wound healing cannot be seen from the outside until it is opened. It is not known when to change the bandage again. To solve these problems, researchers have developed a sophisticated bandage. It is named Smart Bandage.

The research team of Stanford University in America has developed this smart bandage. The head of this research team, Professor Yuanwen Jiang, said that the smart bandage was mainly designed for diabetic patients. Once a wound is formed in the body of diabetic patients, it does not want to heal easily. And with the opportunity to heal the wound too late, bacteria easily grow in the wound. And instead of healing the wound, it worsens. In such cases this smart bandage will work like magic. The researchers claim that it can heal wounds at least 25 percent faster than ordinary bandages.

How does this smart bandage work? In that context, Professor Jiang said, this bandage has a special type of electronic circuit. This circuit includes a sensor to sense the wound temperature. That sensor sends a message about how fast the wound is healing in that circuit. Analyzing that message, if the speed of wound drying is slow, the circuit automatically sends electrical waves to reduce bacterial infection in the wound and contract the tissue in that area. The novel bandage was applied to the wounds of mice in the laboratory to test its effectiveness. It showed that the wound healed at a rate at least 25 percent faster than that of mice given a simple bandage. In addition, the speed of new skin formation at the wound site increased at least 50 percent more than normal. This smart bandage is only 100 microns thick. That is equal to the hair on the human head. The bandage contains microcontrollers, radio antennas, memory, electrical stimulators, biosensors, and more. The underside of this bandage is rubbery or very leathery

As hydrogels have been used. It collects the required information from the biosensor. It also acts as an electrical stimulator. This electrical stimulation works to prevent skin infection and heal damaged tissue. The Smart Bandage works by increasing blood flow to the wound to aid in the formation of new skin. This smart bandage enhances the activity of a gene called Selinp that reduces inflammation in the human body. It also helps to activate another gene called Apoi. This apoi gene is responsible for making skin and soft tissues in the body.

Let me tell you about a new type of bandage. It is also a smart bandage. However, the information about how dry the wound is in this bandage is known through the smartphone. After downloading a specific app, the information from the circuit in this smart bandage can be seen directly in that app. As a result, there is no need to open the bandage and see the condition of the wound. It also indicates when the bandage needs to be removed. The bandage was developed by Ravinder Dahiya, a fellow at the American Institute of Electrical and Electronics Engineers, and a research team from the Bendable Electronics and Sensing Technologies Group at the University of Glasgow. This 5 cm by 6 cm bandage measures the patient’s body temperature after being applied to the wound. It also determines how much pressure can be applied to the wound. The pressure on the wound can be increased and decreased as needed through a smart phone app. The researchers claim that the wound drying process is faster than usual in this method. According to Dahiya, applying this bandage on the chest of a patient who has respiratory problems can give an indication of the extent of irregular breathing.
