'Smart bandaged plaster' which checks the condition of injury and also carries out proper medication

Although wounds (cuts) can be cured even if left unattended, there is also the possibility of becoming an infection on the one hand, it is actually the main cause of amputation of the world's atraumatic limbs, and in the United States more than 25 million living It is said that it is affecting. Although adequate medication can increase the cure rate, it is not possible for a doctor to check it all the time, so it is thought that appropriate dosing by "smart bandage" (medicine) built-in medicine is considered.

According to Professor Samya Sonkasser of Tufts University , "chronic wounds" are increasing as lifestyle diseases increase. As mentioned above, wounds are the major cause of amputation of limbs other than war, so Sonkasser et al. Developed "smart bandage" as a countermeasure.

Normally healed wounds have a pH value in the range of 5.5 to 6.5, but infected wounds that have not healed show a pH value higher than 6.5, so smart bandages incorporate sensors to detect pH and temperature Confirm the healing condition of the wound. When necessary, the microprocessor which reads data from the sensor heats the gel and releases the medicine.

The thickness of the smart bandage is less than 3 mm, the microprocessor part can be reused. The other parts are disposable and it is made possible to make it at low cost.

Professor Sonkasser says that by changing sensors and antibiotics built in, smart bandages may be able to deal with a wide range other than wounds.
