Monitoring wound healing

The skin forms a formidable protective barrier against external physical threats, microbes, chemical agents, radiation, and electric current. Essentially, the skin consists of three primary layers: the epidermis, the dermis, and the subcutaneous tissues. A wound is a breach of the integrity of the skin. Wound treatment forms a significant burden to healthcare system. Hard-to-heal wounds, chronic wounds, are persistent and costly to treat. In recent years, a variety of new technologies has been proposed as an alternate for the conventional monitoring of wounds. One such technology utilizes the bioimpedance measurement. The impedance of the skin is exceptionally high in comparison to the underlying tissue layers. A breach in the skin alters the electrical properties of the skin remarkably. This notion has been utilized in application of bioimpedance method for monitoring of wound healing.
