Engineering a Better Life

Imagine controlling a machine with your mind. Sound like fantasy? At DU, it's becoming a reality that could help more than a million people.

Brain Scan

This new device will allow amputees to control prosthetics with their mind.

Rahmat Shoureshi, dean of Engineering and Computer Science, received a $295,000 National Science Foundation grant to develop brain-imaging technologies that may soon allow amputees to control electronic prosthetics with just a thought.

For a soldier back from Iraq, the victim of a sports accident or the survivor of a traffic mishap, the technology could change lives. In documents supporting the grant, Shoureshi notes that there are about 1.6 million Americans living with the loss of one or more limbs.

"What we are trying to do is develop systems that allow individuals who have physical disabilities and have prosthetic devices to be able to directly control those with a natural motion," Shoureshi explains.

Shoureshi is working closely with DU PhD candidate Chris Aasted, a student he has known since Aasted was a high school senior.

Making it accessible

The exciting part, Shoureshi says, is that this new technology uses light waves that peer inside the human brain without surgery and in real time.

Patients would wear a slim, lightweight scanner on their head. The light waves would "read" activity in carefully mapped areas of the brain, and then convert the thought of movement into an electronic signal to the prosthetic. Thinking about moving an artificial arm or a leg would make it actually move.

The goal is to achieve that in an affordable, easy-to-use device that would work without the patient having to shave their head.

Helping veterans

Shoureshi is excited about the immediate benefit to the growing number of soldiers being injured in Iraq and Afghanistan.

"In these wars, there are 21-year-old, 22-year-old soldiers coming back injured. They have their whole lives ahead of them. This could change everything for them," he says.

"Of all of the research projects I’ve worked on, if this works, this would be the most exciting project I’ve ever undertaken."
