Electroactive Material for Wound Healing

Electroactive Material for Wound Healing (LAR-TOPS-194)
Wound healing facilitated by electrical activity
Overview
This technology is a device that uses electrical activity to facilitate the wound healing process while protecting the wound. The bandage is made of an electroactive material (pictured above) that is stimulated by the heat of the body and the pressure of cell growth, thus no external power source is required.

The Technology
An electroactive device is applied to an external wound site. This method utilizes generated low level electrical stimulation to promote the wound healing process while simultaneously protecting it from infection. The material is fabricated from polyvinylidene fluoride, or PVDF, a thermoplastic fluoropolymer that is highly piezoelectric when poled. The fabrication method of the electroactive material is based on a previous Langley invention of an apparatus that is used to electrospin highly aligned polymer fiber material. A description of the fabrication method can be found in the technology opportunity announcement titled "NASA Langley's Highly Electrospun Fibers and Mats," which is available on NASA Langley's Technology Gateway.
