bobj, glad you liked the article. I hope you were doing all that running on earth, not concrete. This technology is very much in its infancy, as are most of the discoveries I write on reported by universities, instead of commercial companies. That said, hydrogels as a class have a history as cartilage replacements already, so the timeline might be shorter than "normal," if there is such a thing. I guess growing up in Silicon Valley makes me appreciative of Heiseneberg. Anyway, I also have hip issues, although so far only in winter.
Years ago, 35 to be exact, my wife and I enjoyed running-10Ks mostly. Well, father time has put an end to that activity but the "remains of the day" linger. I have real problems with my right hip and right knee. Hip replacement surgery has been recommended but I have put it off for several months due to schedule and the fact that I'm 168 pounds of rompin stompin coward. I talked with my doctor about repairing the cartilage in the joint but he tells me the repair, if possible at all, would be considerably worse than the replacement. With that being the case, Ann do you have a time-line for commercialization of the hydrogels or is this technology in its infancy--tried but unproven? Great article also.
Mydesign, replacement knee surgery is not a sure thing re results, not at all guaranteed, can cause a lot of problems and is insanely expensive: at least half the cost of a low-end car. Otherwise I would have done it by now. Also, most replacement knee implants/structures are engineered for men, not women. But you probably know all that. Meanwhile, any claims of technologies that regrow cartilage are, AFAIK, untrue.
Ann, I had done a bit research for my mother having the same problem. She has some wear and tear in her knee cartilage and doctors advising us for a complete knee replacement. We are looking for some alternate therapy, which can regenerate the cartilages. Eventhough many are clamming that it can be regenerate, but so far nothing is medically proven.
Rob, I think it's both: I do like finding obscure but weird and potentially earth-shaking developments in technology of several kinds. It's also true that we have more researchers now than ever before in many different disciplines, countries and cultures, working on many different solutions to many different problems. Humans have been ingenious creatures for hundreds of millenia: these advances aren't nearly as earth-shattering and shocking as the first sentences, or the first tools, or the first wheels.
I wonder if anyone is working on a substance that could contract to a fraction of its original length, simulating a muscular contraction. If such a substance could be interfaced with nerves it could replace lost muscles and limbs -- and think of the possibilities for robotics without motors.
NIST's new five-year strategic plan for its Material Measurement Laboratory lists additive manufacturing materials development as one of the main areas it will support by developing measurements, data, techniques, and models.
