[New Product] Smart electronic bandage

1. Brief introduction of the results

Intestinal wound healing is a long-standing problem, and traditional suture-based intestinal closure surgery often leads to postoperative problems. Therefore, researchers have been looking for alternative strategies or devices that can effectively heal wounds. In this regard, the R&D team designed a flexible, biodegradable, self-powered electronic bandage that can provide dual-mode electrical stimulation to synergistically accelerate and improve intestinal wound healing and significantly reduce postoperative complications.

This achievement uses dual electrical stimulation to promote wound healing: pulse electrical stimulation induces epithelial cell electrotransfection and promotes the expression of healing factors (such as epithelial growth factor); there is also a direct current stimulation that can enhance the secretion of healing factors in transfected cells. The electronic bandage has a high transfection efficiency and cell viability for intestinal epithelial cells in vitro, and can promote the expression of epithelial growth factor during surgery. Its self-powered primary battery is composed of magnesium and molybdenum microelectrodes to promote the extracellular secretion of healing factors. After the wound is healed, the electronic bandage can self-degrade in the body without the need for secondary surgery to remove it.

2. Application fields

Application scenarios such as clinical intestinal wound recovery.

3. Application prospects

This smart electronic bandage provides a promising way to accelerate wound healing using a dual electrical stimulation strategy. Similar biodegradable electronic bandages can also be used to promote wound healing in other organs and tissues, including the nervous system, skin, and muscles, and have broad clinical application market prospects.

4. Intellectual property

Many patents have been approved, all of which are held solely by the achievement unit.
