Optical sensors help the brain control prosthetic limbs

Scientists at Southern Methodist University in the United States have studied a sensor that can receive nerve impulse optical signals, helping to gradually improve the link between the body's nervous system and the prosthetic limb. .

In the future, through this device the brain can directly control the operation of the prosthesis, the person attached to this device can feel the pressure and heat through the prosthesis.

Currently, the synapses in the prosthetics are made of electronics, in which metal parts can be eliminated by the body. However, optical sensors that capture the neurological signals produced by US scientists are made of fiber and polymer, so not only can they adapt to the body's immune response, but no erosion.

According to scientists, the sensor is in the early stages of manufacturing, but also large size so temporarily can not be installed in the human body. However, when the size of the sensor is shrunk, it can work in the body.

Scientists plan to test the device in cats or dogs over the next two years. However, some experts are skeptical about whether the sensor is completely immune to the body's rejection.
