Wisconsin / Beijing: US and Chinese scientists have jointly researched and developed a bandage that can not only heal a wound quickly but also repair broken bones in a short time by generating electricity for itself. ۔
Not only that, but after the work is done, the bandage itself dissolves into harmless substances inside the body.
It should be noted that recent research has shown that electrical stimulation (slight excess electricity) on the affected part of the body significantly reduces the time required for wound healing and broken bones.
However, to provide additional voltage to the wound or affected area, metal electrodes will also be required, which will require two separate operations to be inserted and removed in the body, which is a separate painful procedure in itself.
To solve this technical problem, Chinese experts from various research institutes in the United States and China have developed this strip, which has been initially tested successfully in mice.
The base layer of this strip is made of a harmless polymer that has already been approved by the US Food and Agriculture Organization (FDA).
Above the polymer layer is attached a tiny electric device called a “triboelectric nano-generator”.
In this way, the layers of two different substances in the power generating devices move closer and farther away from each other due to the movement around them, resulting in very little electricity.
According to a report published in the latest issue of the online research journal Proceedings of the National Academy of Sciences , the invention was called “Fracture Electro Stimulation Device” or “FED” for short. Named. That is, it is a device that produces “electrical stimulation” at the site of a broken bone.
In size and design, it looks like a normal bandage to be applied to a wound, but on closer inspection, you can see the Tribu Electric Nano Generator installed in it.
During the experiments on rats, it was tested on rats whose leg bone was broken in the middle and they were unable to walk.
The rats that had the bandage on their legs recovered completely in just six weeks, during which time they moved around with great ease.
In contrast, rats that did not have this bandage on their legs took a long time to repair their broken legs, and during rehabilitation they had great difficulty in moving.
The “FED” was a constant current of about four volts during these six weeks, but after the leg was connected, it dissolved on its own.
Currently, this experimental strip can only generate electricity by physical movement, which is being further improved to enable it to generate electricity using the body’s internal mechanical energy, such as changes in blood pressure, etc.
At the same time, experiments are underway to make FEDs usable by humans.
It is not clear how long the strip will be available for use in hospitals and emergency centers, as it has yet to undergo several stages of research and development.
