Seeing More with a Needle-Shaped Laser
12-02-22
Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering, and his research team show how they developed a new variant of photoacoustic microscopy (PAM) called needle-shaped beam photoacoustic microscopy (NB-PAM). NB-PAM has a depth of field nearly 14 times greater than what was achievable before. [Caltech story]

Beaming Clean Energy From Space
10-26-22
Once considered science fiction, technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of Caltech researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed—including to places that currently have no access to reliable power. "This is an extraordinary and unprecedented project," says Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance. "It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world." [Caltech story]

Laser Light Offers New Tool for Treating Bone Cancer
09-20-22
Of the many ways to treat cancer, the oldest, and maybe most tried and true, is surgery. The goal is to remove all of the cancerous tissue while preserving as much of the surrounding healthy material as possible. "It's very hard to grow bone, so if you cut out bone, you basically lose it," says Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering. A new diagnostic imaging technology developed by researchers at Caltech is offering surgeons the ability to make cuts 10 times more precisely, allowing them to preserve as much as 1,000 times more healthy tissue and to give patients easier recoveries.

New Research "UNCOVERS" Hidden Objects in High Resolution
08-11-22
Imagine driving home after a long day at work. Suddenly, a car careens out of an obscured side street and turns right in front of you. Luckily, your autonomous car saw this vehicle long before it came within your line of sight and slowed to avoid a crash. This might seem like magic, but a novel technique developed in the laboratory of Changhuei Yang, Thomas G. Myers Professor of Electrical Engineering, Bioengineering, and Medical Engineering; Investigator, Heritage Medical Research Institute, could bring it closer to a reality. "We can see all the traffic on the crossroads with this method. This might help the cars to foresee the potential danger that one is not able to see directly." explains electrical engineering graduate student Ruizhi Cao. [Caltech story]

Azita Emami Appointed to DARPA’s MEC Group
07-13-22
The Defense Advanced Research Projects Agency (DARPA) has named Azita Emami to the Microsystems Exploratory Council (MEC) for a three-year term beginning this summer. Emami is Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering; Executive Officer for Electrical Engineering; and Director, Center for Sensing to Intelligence. MEC brings over 30 of the brightest scientists and engineers together to identify new areas of development in microsystems science and technology and to recommend future possible research directions. The MEC Group was established by DARPA in 2017 to support its technology offices and provide continuing and independent assessment of the state of advanced microsystem technology as it relates to the U.S. Department of Defense.
