Julia R. Greer, Professor of Materials Science and Mechanics, and colleagues have created nanostructured, hollow ceramic scaffolds, and have found that the small building blocks, or unit cells, display remarkable strength and resistance to failure despite being more than 85 percent air. The general fabrication technique the researchers have developed could be used to produce lightweight, mechanically robust small-scale components such as batteries, interfaces, catalysts, and implantable biomedical devices.

Yu-Chong Tai, Professor of Electrical Engineering and Mechanical Engineering, and colleagues have developed a portable device to count white blood cells that needs less than a pinprick's worth of blood and takes just minutes to run. The heart of the new device is a 50-micrometer-long transparent channel made out of a silicone material with a cross section of only 32 micrometers by 28 micrometers—small enough to ensure that only one white blood cell at a time can flow through the detection region. The stained blood sample flows through this microfluidic channel to the detection region, where it is illuminated with a laser, causing it to fluoresce. [Caltech Release]

Joel W. Burdick, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Bioengineering, and Yu-Chong Tai, Professor of Electrical Engineering and Mechanical Engineering, are developing new technologies to expand their research which has enabled a paraplegic man to stand and move his legs voluntarily. The team has until now used intelligent guesswork to determine which stimuli might work best. But soon, using a new algorithm developed by Professor Burdick, they will be able to rely on a computer to determine the optimum stimulation levels, based on the patient's response to previous stimuli. This would allow patients to go home after the extensive rehab process with a system that could be continually adjusted by computer. [Caltech Release] [ENGenious Progress Report]

Joel W. Burdick, Professor of Mechanical Engineering and Bioengineering, and colleagues are recipients of a 2011 Breakthrough Award by Popular Mechanics for their work that helped a paralyzed man stand. The Breakthrough Innovator Awards are in recognition of "innovators whose inventions will make the world smarter, safer, and more efficient in the years to come." [Popular Mechanics Article]

Mani Chandy, Simon Ramo Professor and Professor of Computer Science; Deputy Chair for Education, and Julian J. Bunn, Principal Computational Scientist at CACR, are working with a group of Summer Undergraduate Research Fellowships (SURF) in CMS, EE, and MCE to building a collection of medical devices that can be connected to a cell phone. "We want to exploit cell-phone technology and the Internet to provide inexpensive health-care tests for the poor in remote rural villages," says Chandy. [Caltech Feature]

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.

Popular Mechanics honored a group of Caltech alumni at its annual Breakthrough Awards ceremony on October 15. Rudy Roy ('07), Ben Sexson ('07), and Daniel Oliver ('07), along with Art Center alum Charles Pyott, received the magazine's Next Generation Award for establishing the nonprofit organization Intelligent Mobility International (IMI). IMI's mission is to empower people with disabilities in developing countries by designing and producing safe, affordable wheelchairs made for the rugged terrain of rural communities. The project originated in 2006, in a Caltech class called Product Design for the Developing World, which is taught each fall by Visiting Professor of Mechanical Engineering Ken Pickar.

Mechanical Engineering student Huaising (Cindy) Ko was named one of only 50 college seniors in the nation to receive a $25,000 Thomas J. Watson Fellowship for a year of "purposeful exploration." Originally Ko chose to major in the biological sciences due to her interest in the field of medicine. However, at Caltech she discovered that the field of mechanical engineering fascinated her and allowed her to do interdisciplinary work related to her interests in medicine. As a Watson Fellow, Ko will be able to embark on another aspect of medicine that interests her: the tension between modern and traditional medicine. [Caltech Press Release]
