A biodegradable and implantable wireless device, which accelerates the regeneration of the nerves and improves the healing of a damaged nerve, is, as far as its creators know, the first example of bioelectronic medication.



The innovation is the brainchild of engineers and material science experts from the McCormick School of Engineering and Applied Science at Northwestern University in Evanston, Illinois, and the Washington University School of Medicine in St. Louis, Missouri. All of them.



The new device delivers regular pulses of electricity to damaged peripheral nerves in rats, following a surgical repair process, accelerating the re-growth of nerves in their legs and promoting the ultimate recovery of muscle strength and control. With the diameter of a small coin and the thickness of a sheet of paper, the wireless device operates for about two weeks before being naturally absorbed into the body.

The team of John A. Rogers and Wilson "Zack" Ray foresees that the devices of this new type will one day be able to complement or replace the pharmaceutical treatments for a series of diseases and injuries in humans. This type of technology, which researchers call "bioelectronic medicine," is able to provide therapy for a clinically relevant time period, and right where it is needed, thereby reducing the side effects or risks associated with conventional implants and , in principle, permanent.



Although the device has not yet been tested in humans, the good results obtained in rats promise to place it as a future therapeutic option for patients with nerve injuries.
