Wired: Lasers Power Pentagon’s Next-Gen Artificial Limbs

Reporter Katie Drummond with Wired magazine has covered the research of SMU engineers Marc Christensen and Volkan Otugen who are working as part of a consortium with industry and other universities to develop technology that will someday help amputees have “feeling” in their artificial limbs.

The research is funded through a $5.6 million grant from the U.S. Department of Defense and industry for a center led by SMU’s Lyle School of Engineering. The goal is to develop revolutionary technology for advanced prosthetic limbs that will help amputees returning from war in Iraq and Afghanistan.

Two-way fiber optic communication between prosthetic limbs and peripheral nerves will be key to operating realistic robotic arms, legs and hands that not only move like the real thing, but also “feel” sensations like pressure and heat.

The Pentagon’s already got brain-controlled prosthetics, and they are a major improvement over old-school artificial limbs. The devices are far from perfect, however. They rely on metal implants, which aren’t compatible with the body’s tissues, and they can only transmit a few signals at a time — turning what should be a simple movement into a Herculean task.

Now, Darpa-funded researchers are convinced they’ve found a way to make prosthetics truly life-like: laser beams.

A team led by experts at Southern Methodist University is making swift progress towards prosthetic devices that rely on fiber-optics, and would offer a wearer the kind of seamless movement and sensation experienced with a flesh-and-blood limb.

“Already, we’re tantalizingly close,” Dr. Marc Christensen, the program’s leader, tells Danger Room. “We haven’t seen anything that’s been a deal-breaker yet.”

It all started in 2005, when researchers at Vanderbilt realized they could trigger a nerve using infrared light. The finding catalyzed a handful of research projects investigating the prospect of laser-powered prostheses, and Darpa last year doled out $5.6 million for the creation of the Neurophotonics Research Center, led by SMU, for the development of prosthetic devices powered by infrared lasers.

KERA: Engineering Hope: Research To Aid Injured Troops

Reporter B.J. Austin with Dallas area Public Radio station KERA has interviewed SMU engineers Marc Christensen and Volkan Otugen who are working as part of a consortium with industry and other universities to develop technology that will someday help amputees have “feeling” in their artificial limbs.

The research is funded through a $5.6 million grant from the U.S. Department of Defense and industry for a center led by SMU’s Lyle School of Engineering.

This week, KERA 90.1 is airing a series of reports: “Engineering Hope: Groundbreaking Research That Could Change Our Lives.” In today’s report KERA’s BJ Austin visits a lab where researchers from North Texas universities are developing the next generation of prosthetic limbs for injured soldiers. It’s cutting-edge research that could allow amputees to move more naturally and sense feeling with their artificial limbs.

In a busy Starbucks, two things make 28 year old Clint Barkley stand out in the crowd: his clean cut good looks and his walk.

Barkley: We were just south of Fallujah in 2005. We ran over a land mine. I lost my left leg. Our gunner lost both of his feet below his knee.

The former Marine from Bedford walks unevenly, slightly stiff, but full of confidence. He wears a ten pound, titanium leg. It attaches mid-thigh and has a computerized knee.

Barkley: It reads your body weight, how you’re moving and it reacts accordingly. I put my heel down then as I go and put all the pressure in my toe it knows I’m taking a step so it releases and kicks the foot back forward for me.

But what it doesn’t do is allow a smooth, natural gait. And the leg does not allow him to feel the gravel in a driveway or the heat of an asphalt parking lot in August. But that could be in his future.

A consortium of scientists and engineers in North Texas and elsewhere are working on a way for the brain, the body’s nerve impulses and an artificial limb to “talk” to each other. That could allow an amputee to “think” about moving an artificial arm or leg and the limb would respond immediately and more naturally. Conversely, the artificial limb would talk to the brain, giving it sensory input, thereby allowing the amputee to “feel.” The research is being led by Marc Christensen, Professor of Engineering Innovation at Southern Methodist University. But, part of the project is taking place in a noisy, unassuming lab at the University of North Texas. That’s where Christensen talked about the research, being funded initially by a 5.5 million dollar grant from the Department of Defense.

Popular Science: A New Interface For Bionic Limbs

Light bridges the communication gap between man and machine

The monthly science magazine Popular Science covered the research of SMU engineers Marc Christensen and Volkan Otugen who are working to develop technology that will someday help amputees have “feeling” in their artificial limbs.

The research is funded through a $5.6 million grant from the U.S. Department of Defense and industry for a center led by SMU’s Lyle School of Engineering.

The Six Million Dollar Man’s robotic arm worked as seamlessly as his natural one. But in the real world, robotic limbs have limited motions and the user can’t feel what he or she is “touching.” a new approach using optical fibers implanted around nerves could transmit more data and let prosthetics speak to the brain.

Previously, scientists surgically connected electrodes to the nervous system, but they seemed to harm the body’s tissues, making the implant fail within months. In 2005, scientists discovered that they could stimulate a neuron to send a message by shining infrared light on it. Last September, DARPA, the Pentagon’s R&D branch, awarded $4 million to a project led by Southern Methodist University engineers to attempt to connect nerves to artificial limbs using fiber optics.

The team suspects that flexible glass or polymer fiber optics will be more flesh-friendly than rigid electrodes. In addition, optical fibers transmit several signals at once, carrying 10 times as much data as their electrical counterparts. “Our goal is to do for neural interfaces what fiber optics did for the telecom industry,” says electrical engineer Marc Christensen, who is leading the SMU group. Transmitting more information faster should give bionic limbs more lifelike movements.

Imagine not being able to pick up a drink, a pen, or even hold a spouse’s hand. For thousands of North Texans living as amputees, that is reality. But, some local engineers are teaming up with medical science to help transform that reality and change lives.

Bernie Diamond of Fort Worth is the picture of health. The former fitness model turned hairdresser was on top of his game. But, three years ago, everything changed in a split second when he was randomly shot while standing outside a home in Dallas.

“I got shot at such a perfect angle that it shot through the wrist and blew out the entire back of my hand,” Diamond said.

After many surgeries and attempts to rehabilitate his left hand, Diamond and his doctors made the decision to amputate his hand just above the wrist.

“I remember I was crying the entire time saying please don’t take my hand, please don’t take my hand,” Diamond said.

He had to learn to function with a prosthetic replacement, which doesn’t allow for much movement. But, that’s what researchers at Southern Methodist University and the University of North Texas are trying to change.

“Today we have very sophisticated robotic arms,” explained Marc Christensen, chair of the electrical engineering department at SMU. “What we’re lacking is a good interface to control them.”

Dr. Gunter Gross at UNT, and Doctors Christensen and Volkan Otugen at SMU are working to create a system of fiber-optic wires and sensors that can replace the vast network of nerves inside a limb.

“It’s a link to send and receive information between the brain and the limb,” explained Dr. Otugen, chair of the mechanical engineering department at SMU.
