New Chip-Based Laser Gyroscope Measures Earth's Rotation

03-05-20

Optical gyroscopes are used in applications such as aircraft navigation systems, while MEMS gyroscopes are found in devices like smart phones. Professor Kerry J. Vahala has developed an optical gyroscope that combines some of the best characteristics of each into one device. "For more than 20 years, researchers have speculated about placing optical gyroscopes onto a chip very much like the highly successful MEMS gyroscopes. But until recently, there have been very few compelling experiments," Vahala says. [Caltech story]

Microstructures Self-Assemble into New Materials

03-03-20

A new process developed at Caltech makes it possible for the first time to manufacture large quantities of materials whose structure is designed at a nanometer scale—the size of DNA's double helix. Pioneered by Professor Julia R. Greer, "nanoarchitected materials" exhibit unusual, often surprising properties—for example, exceptionally lightweight ceramics that spring back to their original shape, like a sponge, after being compressed. Now, a team of engineers at Caltech and ETH Zurich have developed a material that is designed at the nanoscale but assembles itself—with no need for the precision laser assembly. "We couldn't 3-D print this much nanoarchitected material even in a month; instead we're able to grow it in a matter of hours," says Carlos M. Portela, Postdoctoral Scholar. "It is exciting to see our computationally designed optimal nanoscale architectures being realized experimentally in the lab," says Dennis M. Kochmann, Visiting Associate. [Caltech story]

Sweat Sensor Detects Stress Levels; May Find Use in Space Exploration

02-27-20

Wei Gao, Assistant Professor of Medical Engineering, has produced a wireless sweat sensor that can accurately detect levels of cortisol, a natural compound that is commonly thought of as the body's stress hormone. This could allow for more widespread and easier monitoring of stress, anxiety, post-traumatic stress disorder, and depression. "We aim to develop a wearable system that can collect multimodal data, including both vital sign and molecular biomarker information, to obtain the accurate classification for deep space stress and anxiety," Gao says.

Team CoSTAR Takes First Place in Underground Robot Competition

02-27-20

A team including Caltech researchers and JPL earned top honors in the DARPA Subterranean Challenge. Whether robots are exploring caves on other planets or disaster areas here on Earth, they need to be able to navigate a location and seek out objects of interest without access to GPS or human guidance. The Subterranean Challenge tests this kind of cutting-edge technology. "One of the two courses we had to run had multiple levels, so it was great that the Boston Dynamics robots were fantastic on stairs," says Joel Burdick, the Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Bioengineering and JPL research scientist, and the leader of the Caltech campus section of the CoSTAR team. [Caltech story]

Professor Wang Advances Photoacoustic Imaging Technology

02-25-20

Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, has developed variants of photoacoustic imaging that can show organs moving in real time, develop three-dimensional (3-D) images of internal body parts, and even differentiate cancerous cells from healthy cells. Photoacoustic imaging, a technique for examining living materials through the use of laser light and ultrasonic sound waves, has many potential applications in medicine because of its ability to show everything from organs to blood vessels to tumors. Wang has now further advanced photoacoustic imaging technology with what he calls Photoacoustic Topography Through an Ergodic Relay (PATER), which aims to simplify the equipment required for imaging of this type.

Goddard Receives UCLA Samueli Lifetime Contribution Award

02-24-20

Professor William Goddard has been honored with the 2020 UCLA Samueli Lifetime Contribution Award for his significant contributions to the fields of engineering, quantum mechanics, physical chemistry and chemical physics. Goddard obtained his bachelor’s in engineering with highest honors from UCLA in 1960, and frequently collaborates with UCLA faculty members. “Each of Goddard’s academic achievements represents a key advance in its respective field,” said Yu Huang, a professor of materials science and engineering at UCLA. “He has deservedly been recognized nationally and internationally for his highly accomplished academic career and, furthermore, has kept in close touch with UCLA colleagues and maintained fruitful collaborations with numerous UCLA faculty members.” [UCLA story]
