New Process Allows 3-D Printing of Nanoscale Metal Structures

02-09-18

Professor Julia Greer and graduate student Andrey Vyatskikh have created complex nanoscale metal structures using 3-D printing. The process, once scaled up, could be used in a wide variety of applications and opens the door to the creation of a new class of materials with unusual properties that are based on their internal structure.

Professor Wang Elected to the National Academy of Engineering

02-07-18

Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, has been elected to the National Academy of Engineering (NAE). Professor Wang was elected for "inventions in photoacoustic microscopy enabling functional, metabolic, and molecular imaging in vivo." Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer. Academy membership honors those who have made outstanding contributions to "engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature," and to the "pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education."

Engineers Create Stable Plasma Ring in Open Air

11-13-17

For the first time, Professor Morteza Gharib and colleagues have created a stable ring of plasma in open air using just a stream of water and a crystal plate. The team fired the water jet at surfaces of different textures and found that the smoother the surface, the clearer the structure of the plasma ring. The ring is stable, and as long as the water continues to flow, the ring maintains its shape and size. [Caltech story]

Laser-Imaging Technology Brought into Focus

10-26-17

Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, and colleagues have improved a technique for taking three-dimensional (3-D) microscopic images of tissue, allowing them to see inside living creatures with greater precision than before. "This gives us the ability to look through opaque materials and see what's inside," Professor Wang says. "It's like an extension of the human eye, like Superman's X-ray vision."  [Caltech story]

The Science of Sweat

09-29-17

Wei Gao, Assistant Professor of Medical Engineering, is interested in the future of personalized and precision medicine, and is engineering the next generation of wearable health monitors and nanomachines that could enable rapid and hyper-localized drug delivery and surgery. The sweatband health tracker he is developing is capable of studying health at a molecular level. By analyzing an individual’s sweat, the device can monitor dehydration levels as well as blood glucose levels in real time. [Caltech interview]

New Microchip Technology Could Be Used to Track Smart Pills

09-12-17

Azita Emami, Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering; Investigator, Heritage Medical Research Institute; and EAS Division Deputy Chair, along with her colleagues including Professor Mikhail Shapiro have developed microscale devices that relay their location in the body. "We wanted to make this chip very small with low power consumption, and that comes with a lot of engineering challenges," says Professor Emami. "We had to carefully balance the size of the device with how much power it consumes and how well its location can be pinpointed." [Caltech story]

New App Replaces Ultrasound with Smartphone Camera to Measure Heart Health

09-05-17

Professor Morteza Gharib and colleagues including alumni Derek Rinderknecht (PhD '08), Niema Pahlevan (PhD '13), and Peyman Tavallali (PhD '14) and Caltech visitor in medical engineering Marianne Razavi have demonstrated that the camera on your smartphone can noninvasively provide detailed information about your heart's health. "In a surprisingly short period of time, we were able to move from invention to the collection of validating clinical data," says Professor Gharib. [Caltech story]

Professor Emami to Speak at NAE Frontiers of Engineering Symposium

06-23-17

Azita Emami, Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering; Investigator, Heritage Medical Research Institute; and EAS Division Deputy Chair, has been selected as a speaker for the National Academy of Engineering’s (NAE) 23rd annual U.S. Frontiers of Engineering (USFOE) symposium. The symposium will cover cutting-edge developments in four areas: Mega-Tall Buildings and Other Future Places of Work, Unraveling the Complexity of the Brain, Energy Strategies to Power Our Future, and Machines That Teach Themselves. The mission of the NAE is to advance the well-being of the nation by promoting a vibrant engineering profession and by marshalling the expertise and insights of eminent engineers to provide independent advice to the federal government on matters involving engineering and technology.

Ultra-Thin Camera Creates Images Without Lenses

06-22-17

Professor Ali Hajimiri and colleagues have developed a new camera design that replaces the lenses with an ultra-thin optical phased array (OPA). The OPA does computationally what lenses do using large pieces of glass: it manipulates incoming light to capture an image. "Here, like most other things in life, timing is everything. With our new system, you can selectively look in a desired direction and at a very small part of the picture in front of you at any given time, by controlling the timing with femto-second—quadrillionth of a second—precision," says Professor Hajimiri.
