An Engineering Art Exhibit

03-21-13

Hillary Mushkin, Visiting Professor of Art and Design in Mechanical and Civil Engineering, worked with a group of students taking her new media art history seminar (E/H/Art 89 - the first Caltech course cross-listed in engineering and humanities) to conceptualize, design and fabricate their own original new media artwork using technologies and fabrication methods of their own choice. Students created electroencephalogram (EEG) art, automatic drawing machines, conceptual art-inspired visualizations of mathematical concepts, interactive video projections, electronic instruments and other novel forms.

International Scholarship Focused on Engineering Global Challenges Announced

03-14-13

The Caltech Division of Engineering and Applied Science and the USC Viterbi School of Engineering have established a new scholarship program, named after outgoing National Academy of Engineering (NAE) president Charles M. Vest at their institutions, along with six other universities around the country. "The Vest Scholarship is a superb opportunity for high-powered international graduate students to work with faculty and researchers who are international leaders in their engineering disciplines," says Chair Ares Rosakis. "At Caltech, due to its small size and strong interdisciplinary philosophy, the students will have the opportunity to work closely with not only these international leaders in engineering research, but also with their collaborators in all areas of science and technology."

Creating Indestructible Self-Healing Circuits

03-11-13

Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, and colleagues have built electronic chips that repair themselves. The team has demonstrated this self-healing capability in tiny power amplifiers. The amplifiers are so small, in fact, that 76 of the chips—including everything they need to self-heal—could fit on a single penny. In perhaps the most dramatic of their experiments, the team destroyed various parts of their chips by zapping them multiple times with a high-power laser, and then observed as the chips automatically developed a work-around in less than a second.

Sander Weinreb Receives Microwave Pioneer Award

02-28-13

Dr. Sander Weinreb, Faculty Associate in Electrical Engineering, is the recipient of the 2013 Microwave Pioneer Award from the IEEE Microwave Theory and Techniques Society (MTT-S). The Microwave Pioneer Award recognizes individuals who have made outstanding pioneering technical contributions that advance microwave theory and techniques, which are described in an archival paper published at least 20 years prior to the year of the award.

Disease Diagnosis at the Touch of a Button

02-25-13

Axel Scherer, Bernard Neches Professor of Electrical Engineering, Applied Physics and Physics, and colleagues have built a new version of a polymerase chain reaction (PCR) device, which generates many copies of a pathogenic nucleic acid, allowing the infection to be detected. The device is the result of nearly 10 years of research at Caltech. In 2004, Scherer, a leader in the field of microfluidics, and George Maltezos were investigating how to manipulate biological fluids on a chip. While this was an interesting engineering problem, Maltezos began to wonder how he could apply the microfluidic techniques that he was perfecting to real-world problems. Then the H5N1 bird flu pandemic erupted in Asia, and the team had their real-world problem. [Caltech Release]

EAS Division Welcomes New Deputy Chair

02-08-13

Peter Schröder, Professor of Computer Science and Applied and Computational Mathematics, is the new Deputy Chair of the Division of Engineering and Applied Science. "I look forward to working with Peter over the next several years as we continue with our quest to remain a unique collaborative community of isolated singularities that sets a compelling model as a research and teaching institution," says Chair Ares Rosakis.

A New Tool for Secret Agents—And the Rest of Us

12-10-12

Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, and Postdoctoral Scholar in Electrical Engineering, Kaushik Sengupta, have developed tiny inexpensive silicon microchips that generate terahertz (THz) waves that fall into a largely untapped region of the electromagnetic spectrum and that can penetrate a host of materials without the ionizing damage of X-rays. When incorporated into handheld devices, the new microchips could enable a broad range of applications in fields ranging from homeland security to wireless communications to health care, and even touchless gaming. "This extraordinary level of creativity, which has enabled imaging in the terahertz frequency range, is very much in line with Caltech's long tradition of innovation in the area of CMOS technology," says Chair Ares Rosakis. "Caltech engineers, like Ali Hajimiri, truly work in an interdisciplinary way to push the boundaries of what is possible." [Caltech Release]

Point of Light

12-07-12

Hyuck Choo, Assistant Professor of Electrical Engineering, and Postdoctoral Scholar Myung-Ki Kim have invented a light-focusing device that may lead to applications in computing, communications, and imaging. This new kind of waveguide is made of amorphous silicon dioxide and is covered in a thin layer of gold. Just under two microns long, the device is a rectangular box that tapers to a point at one end. With the new device, light can ultimately be focused in three dimensions, producing a point a few nanometers across, and using half of the light that's sent through, Choo says. (Focusing the light into a slightly bigger spot, 14 by 80 nanometers in size, boosts the efficiency to 70 percent). The key feature behind the device's focusing ability and efficiency, he says, is its unique design and shape. [Caltech Release and Video]

Progress for Paraplegics

10-25-12

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]
