Bionic Arm

08/14/2006 9:15 AM

"Gentlemen, we can rebuild him. We have the technology. We have the capability to make the world's first bionic man. Steve Austin will be that man. Better than he was before. Better ... stronger ... faster."

Well, maybe not better, faster, or stronger yet, but it works. A man in Dayton Tennessee has two prosthetic arms and is painting his house and using a ladder to do it. It's possible because one of the arms is bionic and controlled by his thoughts.

Doctors describe Sullivan as the first amputee with a thought-controlled artificial arm. Millions were spent on the technology, and a researcher says the retail price would be about $100,000 for a pair. But doctors have asked Sullivan not to pamper the arms. Sullivan's prosthetic right arm is relatively simple, a motor-operated limb with a hook. But his thought-controlled bionic arm represents a real advance. The U.S. government, spurred by the growing count of soldiers who have lost limbs in Iraq and Afghanistan, is spending millions of dollars and working with universities and private companies to develop artificial limbs that connect body and mind.

Sullivan said he's proud to test the bionic arm for such soldiers. "Those guys are heroes in my book, and they should have the best there is," Sullivan said. "Hopefully they have got 60 or 70 years in front of them." The military's research-and-development wing — known as the Defense Advanced Research Projects Agency, or DARPA — wants to develop a mechanical arm that mimics the real thing by 2009.

At a previous job I worked on an artificial muscle project. The muscle was a liquid crystal elastomer which is a flexible polymer with liquid crystals inside. By heating the LCE we could get it to contract as the liquid crystal went from Nematic phase to Isotropic phase. Really interesting work.

"has two prosthetic arms and is painting his house and using a ladder to do it."

All this time I have been using a brush to paint my house!

My bad, I'll clarify:

He's climbing the ladder to get to part of the house he wants to paint, not using the ladder to paint. He's using a roller brush to paint. Though if it were truly a bionic arm, he should be able to use the ladder to paint.

Booming Business

This technology interests me quite a bit. I had first heard about this story over a year ago. Sadly, the number of soldiers coming back with limb amputations is huge. This is a direct result of advanced body armour and quick medical response as well as the type of urban / guerilla warfare being fought. Before, soldiers injured in an explosion would bleed out long before medical help could save them.
Last fall, I saw a presentation by the inventor of the C-Leg, a new prosthetic knee. He said that the demand for these devices is huge, much more than would be expected if it weren't for the war overseas. The part that bothers me is that the US government wants to bring his device up to military specifications so they can send the soldiers back into duty.

As horrific as war is, it sure does wonders for advancing technology...

I wish we could protect the limbs of the soldiers better. Why doesn't body armor extend over the entire body?
