Digital bandage treats chronic wounds

The digital bandage, developed by Dr Ali Tamayol, associate professor, and researchers from the University of Nebraska-Lincoln and Harvard Medical School, is said to be equipped with miniature needles that can be controlled wirelessly, allowing the drugs to be programmed by medical staff without visiting the patient.

New bandage clots blood but doesn’t stick to wound

"This is an important step in engineering advanced bandages that can facilitate the healing of hard to treat wounds. The bandage does not need to be changed continuously," Tamayol said in a statement.

Chronic and non-healing wounds – a complication of diabetes that can lead to limb amputation - affects millions of people each year. Due to the complex nature of these wounds, proper clinical treatment has been limited.

Given the range of processes necessary of wound healing, different medications are needed at different stages of tissue regeneration. Consequently, this requires the development of wearable devices that can deliver agents to critical layers of the wound bed in a minimally invasive way.
