Flexible Neural Implant Allows Paralyzed Rats to Walk Again
From: Engineering TV Weekly Update - 04/27/2015

Scientists at Switzerland's Ecole Polytechnique Federale de Lausanne (EPFL)
have enabled paralyzed rats to walk on their own again using a combination of
electrical and chemical stimulation. But applying this method to humans would
require multifunctional implants that could be installed for long periods of
time on the spinal cord without causing any tissue damage. The e-Dura implant
was engineered to solve this problem by being as flexible and stretchable as
living tissue. In tests on paralyzed rats, the implant proved its
biocompatibility and the rats regained the ability to walk on their own again
after a few weeks of training.
