Stimulating Electrode Array Assists Paraplegic Man to Stand and Move Legs Voluntarily

05-20-11

Joel W. Burdick, Professor of Mechanical Engineering and Bioengineering, and colleagues including Yu-Chong Tai, Professor of Electrical Engineering and Mechanical Engineering, have used a stimulating electrode array to assist a paralyzed man to stand, step on a treadmill with assistance, and, over time, to regain voluntary movements of his limbs. Using a combination of experimentation, computational models of the array and spinal cord, and machine-learning algorithms, Professor Burdick and his colleagues are now trying to optimize the stimulation pattern to achieve the best effects, and to improve the design of the electrode array. Further advances in the technology should lead to better control of the stepping and standing processes. [Caltech Press Release]

Experiments Settle Long-Standing Debate about Mysterious Array Formations in Nanofilms

05-19-11

Sandra M. Troian, Professor of Applied Physics, Aeronautics, and Mechanical Engineering, and colleagues' experiments have confirmed which of three possible mechanisms is responsible for the spontaneous formation of three-dimensional (3-D) pillar arrays in nanofilms (polymer films that are billionths of a meter thick). "My ultimate goal is to develop a suite of 3-D lithographic techniques based on remote, digital modulation of thermal, electrical, and magnetic surface forces," Troian says. Confirmation of the correct mechanism has allowed her to deduce the maximum resolution or minimum feature size ultimately possible with these patterning techniques. [Caltech Press Release]

Caltech Engineering Ranks High on U.S. News Best Grad Schools List

03-15-11

Caltech continues to rate among America's top graduate engineering programs, according to the 2012 U.S. News & World Report list of the best grad schools. U.S. News surveyed administrators at more than 1,200 programs and 13,000 academics and professionals to determine the rankings, which place Caltech among the top five schools in the country in several engineering programs, including first in Aeronautical Engineering, fourth in Mechanical Engineering, and fifth in Electrical Engineering. Overall, the engineering graduate program was rated seventh in the nation. The program, which is among the nation's smallest, was singled out as being the most selective, admitting only 9 percent of prospective students. "Given our minute size, these rankings are great," said Chair Ares Rosakis.

Engineering Design Competition: "Extreme Recycling"

03-10-11

Congratulations to Chris Hallacy, Brad Saund, and Janet Chen for winning the 27th Annual ME72 Engineering Design Competition! "Extreme Recycling" was the theme of this year's competition. Teams designed, built, and deployed vehicles that traversed difficult terrain in order to gather a variety of recyclables, correctly sort recyclables into bins, and return vehicles to the start zone by the end of each heat.

Professor Blanquart Receives NSF CAREER Award

02-25-11

Guillaume Blanquart, Assistant Professor of Mechanical Engineering, has been awarded the National Science Foundation's (NSF) Faculty Early Career Development (CAREER) Award for his proposal entitled "Towards understanding and modeling turbulent buoyant flows". The aim of the project is to understand the complex interactions between turbulent fluid mechanics and Rayleigh-Taylor instabilities. These phenomena commonly occur in nature such as in supernova explosions, under water hot-vents, and fires. They are also encountered in many engineering applications such as in Inertial Confinement Fusion.
