NASA develops electric bandage that heals wounds
Q. NASA has developed a new high tech material that uses electricity to promote healing of injured wounds. What is it called?- Published on 12 Oct 16a. Polysaccharide Fluoride
b. Polyvinyl Fluoride
c. Polyvinylidene Fluoride
d. None of the above
ANSWER: Polyvinylidene Fluoride
NASA has developed a new high-tech material that employs electricity to promote healing of injured woulds.
- Where there is non-Earth gravity, human blood displays behaviour quite differently from earth
- Wounds heal more slowly and considering the costly space missions and survival risks, healing of wounds as fast as possible is crucial
- The new material generates a small amount of electricity while interacting with another surface including human skin
- Material called polyvinylidene fluoride has numerous possible applications including wound healing
- Wounds tend to heal more quickly if small amounts of electricity are applied to the surrounding tissue
- The gauze pattern is also essential to the healing process
- If the PVDF fibres are aligned correctly, cells on a wound use it as a scaffold, helping faster healing of the wound
- The easiest way to align the fibres is to make gauze which creates an additional layer of protection against infection
- The invention is a simple and inexpensive means of producing fibres and mats of controlled fibre diameter, thickness and porosity.
- The device can be used by military personnel in the field, those undergoing surgery or those with serious injuries
