Disease Diagnosis at the Touch of a Button


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


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.

Professor Gharib Named Charter Fellow of the National Academy of Inventors


Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Professor of Bioinspired Engineering as well as Caltech Vice Provost for Research, has been named a charter fellow of the National Academy of Inventors (NAI). Academic inventors and innovators elected to the rank of NAI Charter Fellow are nominated by their peers "for outstanding contributions to innovation in areas such as patents and licensing, innovative discovery and technology, significant impact on society, and support and enhancement of innovation."

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


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]

3-D Dentistry


Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Professor of Bioinspired Engineering as well as Caltech Vice Provost, has designed a handheld device, that has three apertures which take a picture of the tooth at the same time, but from different angles. The three images are then blended together using a computer algorithm to construct a 3-D image. His imaging innovation will ease your trip to the dentist and may soon energize home entertainment systems too. "Professor Gharib is as brilliant a scientist as he is an engineer and inventor," says Chair Ares Rosakis. "I think that's what we have to do to look at humanity's big problems: we have to be ready to act as pure scientists when we observe and discover as well as act as practical engineers when we invent and apply. This continuous interplay happens at Caltech better than at other institutions." [Caltech Release]

Knowing When to Fold 'Em


Electrical engineer Azita Emami-Neyestanak is an expert in the 21st century technology of analog and digital circuits for computers, sensors, and other applications, so when she came to Caltech in 2007, she never imagined that she would be incorporating in her research an art form that originated centuries ago. But origami—the Japanese art of paper folding—could play a critical role in her project to design an artificial retina, which may one day help thousands of blind and visually impaired people regain their vision.

Progress for Paraplegics


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]

Seeing Inside Tissue


Changhuei Yang, Professor of Electrical Engineering and Bioengineering, and colleagues Ying Min Wang and Benjamin Judkewitz have developed a new method to focus light inside biological tissue. "It enables the possibilities of doing incision-less surgery," says Professor Yang. "By generating a tight laser-focus spot deep in tissue, we can potentially use that as a laser scalpel that leaves the skin unharmed." [Caltech Press Release]

Professor Gharib Becomes a Fellow of the International Academy of Medical and Biological Engineering


Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Professor of Bioinspired Engineering, has been elected as Fellow of the International Academy of Medical and Biological Engineering. Fellows are selected because they have made identifiable contributions to the theory or practice of medical and biological engineering, and have demonstrated unusual accomplishment in promoting the field of medical and biological engineering.

Naturally Inspired


Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Professor of Bioinspired Engineering, and colleagues are studying the properties of the zebrafish embryonic heart to address problems as diverse as ringing in the ears and overheated electronics. They have also developed the first pump built entirely from biological building blocks. “We can actually be more clever than nature,” Gharib says. “We can get inspired by nature and use engineering to come up with better functions. Just look at 747s—they fly from LAX to La Guardia much more efficiently than any bird could.” [E&S Article]
