Thought-Controlled Prosthesis Changing Lives of Amputees

Slow step-wise progress is being made toward achieving bionic style prostheses we've seen in TV fiction decades ago.

The world's first implantable robotic arm controlled by thoughts is being developed by Chalmers researcher Max Ortiz Catalan. The first operations on patients will take place this winter.

This research project is using the world-famous Brånemark titanium implant instead (OPRA Implant System), which anchors the prosthesis directly to the skeleton through what is known as osseointegration.

"Osseointegration is vital to our success. We are now using the technology to gain permanent access to the electrodes that we will attach directly to nerves and muscles," says Max Ortiz Catalan.

Max Ortiz Catalan demonstrates how the system works with the aid of electrodes, which capture bio-electric signals from the surface of the arm. Amputees will, however, have the electrodes implanted directly on the nerves and muscles inside the body,...
