The image of the developed smart bandage is as follows. It looks more like a bandage than a bandage, and it can be seen that it has small devices like electrodes and cords that each extend.

The smart bandage has an ultra-small needle that can be controlled wirelessly using a smartphone-sized proprietary device. The ultra-small needle reaches the deeper layers of the skin with minimal pain and inflammation, allowing for efficient dosing. Also, it seems that you can select the medicine to be administered from the built-in medicine. The image below shows an image of a very small needle inserted into the skin.

Smart bandages are primarily intended for diabetics. Diabetes with chronic insulin deficiency can make it difficult for diabetic patients to heal even small wounds, sometimes resulting in severe wounds, because insulin deficiency promotes the breakdown of proteins needed to heal the wound. In the United States, diabetic patients are considered to have complications associated with non-healing wounds, and millions of patients are suffering from severe complications such as amputation each year.

In the treatment of wounds in diabetics, different drugs need to be administered depending on the progress of cell regeneration. This is why smart bandages were designed to deliver different drugs. And with wireless control, patients can take medication without visiting a healthcare facility or having a doctor visit the patient.

The research team also experimented with wearing a smart bandage on diabetic mice with wounds on the skin. As a result of the experiment, the wound on the mouse was healed completely, and no scars were seen. With this result, the researchers claim that smart bandages can significantly improve the speed and quality of wound healing in diabetes, and significantly reduce the rate at which wounds become chronic.

Ali Tamayol, the lead researcher, reported that he has applied for a patent on technology for smart bandages.
