Experts from Stanford University, USA, announced that tissue repair of a person with chronic wounds can be accelerated by increasing blood flow to the injured tissue, which causes the wound to close in a shorter time than traditional dressings. a14s
In addition to accelerating healing, the idea — which has an impedance and temperature sensor — can also communicate with a smartphone to monitor it in real time, a process similar to what happens with the use of smart watches. Check the information.

Studies indicate that the impedance of an injured region begins to increase as healing progresses, and Stanford University scientists put two layers of the smart bandage in addition to a layer of polymer film that is only 100 microns thick. In the “device”, the part that comes into with the skin is made of hydrogel and acts to close the wound as soon as possible.
The development was mainly carried out to help people diagnosed with diabetes or who have a suppressed immune system, who often end up having more frequent infections or inflammation due to the slower healing process in their body.
More severe cases of diabetes may even require amputation of the injured part so that a large infection does not spread throughout the body. The costs of treating people with this type of problem reach US$ 25 billion per year worldwide.
The creators of Fast Healing Smart Bandage observed that smart dressing accelerates healing by 25% in mice; skin regrowth time increased by 50% in tests also done on mice.

Healing is accelerated by sending a small, painless electrical current that can act to treat an open wound. In addition to the impedance sensor, the Fast Healing Smart Bandage has a temperature sensor used to know how healing happens over time.
So that the removal of the smart bandage is not necessary to assess the evolution of healing, a very common action nowadays, the specialists also managed to place a radio antenna, memory, electrical stimulator and central processing unit that exchanges information with a smartphone so that the monitoring is carried out in real time.
O Fast Healing Smart Bandage it can be removed when the temperature of the previously injured area is stable. Removal is simple: just heat the body part up to 40Cº and the hydrogel will automatically make the device fall off the skin.
Availability on the market 2v346j
Like any new treatment, scientists need to work on larger prototypes for humans and, above all, lower production costs for the smart dressing to be launched on the market.
There is still no definite estimate of when the Fast Healing Smart Bandage should reach the world market, but the scientists signaled that more sensors can be coupled to the idea for measuring pH, metabolic and other biomarkers. Everyone involved can also learn more about the healing process so that new methods can be created in the future.
We think it represents a new modality and will allow for new biological discoveries and the exploration of previously difficult-to-test hypotheses about the human healing process.
