Muscle Tissue Engineering
Hugh Herr, PhD spoke on the future technology of muscle tissue engineering. His area of specialization is in "actin-myosin machines": muscle-driven micro robots that feed on glucose. Current research is focused on marine invertebrates due to their simple circulatory system. Lab tests have shown that cultured muscle tissue from these simple animals, floating in a glucose-water solution, reacts to stimuli in a manner similar to human muscle tissue except with a weaker contraction. Dr. Herr speculated that genetic engineering might be needed to increase the strength characteristics of such biological machines.
His first actin-myosin robot will be a 3-centimeter fish with an articulated tail. It will swim around continuously in a sugar-water environment that provides both nutrition and buoyancy. Later, larger fish will be constructed as this actuator technology develops further.
Dr. Herr is also a bilateral transtibial amputee, so he is acutely aware of the limitations of current prosthetic technology. A book about his experiences as a new amputee titled Second Ascent: The Story of Hugh Herr has been written by mountain climber-author Alison Osius [ISBN 0-8117-1794-1].

hydraulic knee joint
In the past I have worn KAFO's because of instability of my joints due to having a rare connective tissue disorder. These were custom made, and of the 'cosmetic' plastic style.
This year I had major spinal surgery that led to damage to ... read more

Re: polycentric knee joints
Although I'm not an engineer, I believe this is an interative process. Some years ago, Professor Radcliffe demonstrated a simple program he had written that allowed him to specify different link geometries which produced animations of the ... read more

Re: mountain climber amputee
You may have already gotten your answer (it is probably too late anyway), but I think the person you are asking about is Ed Hommer. He wrote a book about his life called "The Hill". He also has a web page at www.everestquest.com, which ha... read more
