Successful development of artificial arm that can feel like real

Currently, this artificial arm has achieved almost 100% accuracy after testing.

DARPA - the Defense Advanced Research Projects Agency under the US Department of Defense - has completed the development of an artificial arm for amputees with the ability to feel like a normal arm. The first person to use the arm is a 28-year-old spinal cord injury patient who has been paralyzed for nearly 10 years. This prosthetic arm will be linked to the patient's brain so that he can feel what he is touching.

Justin Sanchez, head of the development program, said that controlling artificial parts has really stepped up to a new level when feedback from the contact surface has been analyzed more specifically and created something called "artificial senses" to support patients more effectively. Clinical trials through attaching electrodes to the cerebral cortex of volunteers participating in the study have shown positive results when the signal transmitted to the brain is relatively stable and does not cause side effects. Currently, this artificial arm has reached almost 100% accuracy after testing.

The artificial arm, designed by the Johns Hopkins University Robotics Laboratory and DARPA, has added the ability to receive sensory signals from physical contact to it, creating a breakthrough for the future of medicine, especially those related to rehabilitation for disabled patients. The key part in this research is the torque sensors that can detect the pressure applied to the surface of this artificial arm.
