News Item UCLA Engineering Plays Key Role in DARPA ‘Neuroprosthesis’ Research

MarkovicSayed

Markovic, Sayed to Work on a $15 Million Project to Restore Memory Function to Victims of Brain Injury

The UCLA Henry Samueli School of Engineering and Applied Science has been tapped by the Defense Advanced Research Projects Agency to play a key role in an innovative project aimed at developing a wireless, implantable brain device that could help restore lost memory function in individuals who have suffered debilitating brain injuries and other disorders.

The four-year effort, to be led by UCLA's Program in Memory Restoration and funded by up to $15 million from DARPA, will involve a team of experts in neurosurgery, electrical engineering, neurobiology, psychology and physics who will collaborate to create, surgically implant and test the new "neuroprosthesis" in patients.

Dr. Itzhak Fried, a professor of neurosurgery at the David Geffen School of Medicine at UCLA and a professor of psychiatry and biobehavioral sciences at the Semel Institute for Neuroscience and Human Behavior at UCLA, is UCLA’s lead investigator on the project.

Dejan Markovic, associate professor of electrical engineering, will lead a group of UCLA Henry Samueli School of Engineering and Applied Science researchers developing technology to stimulate and record the activity of single neurons and of small neuronal populations. Electrical Engineering Professor Ali Sayed will work on signal processing and related aspects of the technology. DARPA will provide $4.5 million over four years for the UCLA Engineering effort, contingent on researchers meeting a series of technical milestones.

UCLA partners include the Lawrence Livermore National Laboratory and Stanford University.

Memory is the process by which neurons in certain brain regions encode, store and retrieve information. Various illnesses and injuries can disrupt this process, causing memory loss. Traumatic brain injury, which has affected more than 270,000 military members since 2000, as well as millions of civilians, is often associated with such memory deficits. Currently, no effective therapies exist to address the long-term effects of these injuries on memory.

This ambitious, first-if-its-kind project at UCLA builds on Fried's 2012 research demonstrating that human memory can be strengthened by stimulating the brain's entorhinal cortex, a region involved in learning, memory and Alzheimer's disease.

In a key part of the project, the research team will stimulate and record neuron activity in patients who already have brain electrodes implanted as part of epilepsy treatment. Researchers will use this information to develop computational models and determine how to intervene with electrical stimulation to help restore memory function. The models will be transformed into therapeutics using technology developed by Markovic‘s team.

Markovic said the goal is to create miniature wireless neural sensors that are far more sophisticated — much smaller and with much higher resolution — than those that exist today. The sensors will track and modulate neural activity with very precise spatial and temporal resolution, allowing the device to continuously update and modulate patterns of stimulation to optimize therapy and restore memory function.

“We are developing ultra–low-power electronics in order to measure activity of specific areas of the brain, perform neural signal analysis and wirelessly transmit that information to an outside device in close proximity to the implants,” Markovic said. “The implants and the outside device will talk to each other. The goals are to provide better therapy for people with neurological dysfunction and help those with epilepsy and brain injury to enhance and restore memory.”

During the second phase of the program, Fried, using a minimally invasive procedure, will implant the device in patients with traumatic brain injury as part of a groundbreaking clinical trial.

The DARPA initiative aimed at developing these implantable brain devices, Restoring Active Memory (RAM), supports President Obama's BRAIN initiative.

News Item Prof. Rob Candler is Awarded a $1 Million Grant by the W. M. Keck Foundation

Robert CandlerAssistant Professor Robert Candler received a $1 million research grant from the W. M. Keck Foundation for his research entitled “Ultra-compact X-ray Free Electron Laser.” This is a 2-year endeavor which aims to produce a miniaturized free electron laser by combining novel nanofabrication techniques with cutting edge free electron laser physics, enabling access to new physical regimes of operation that are inherently more efficient. Partnering in this effort are Prof. Rob Candler from Electrical Engineering and the California NanoSystems Institute, Professor Pietro Musumeci from Physics, and Professor James Rosenzweig from Physics.

 

Currently there is only one x-ray laser device capable of producing high-speed and high-resolution imaging for use in chemistry, biology, material science and condensed matter physics, and it is only accessible from a billion dollar class national laboratory. The success of this study will lead to the creation of X-ray Free Electron Lasers (XFELS) that can fit in college laboratories and are capable of producing high brightness x-rays that generate ultrafast, high-resolution images in the x-ray water window. These miniature XFELS, will create a paradigm shift by making this tool for transformational science widely available to scientists.

 

The W. M. Keck Foundation funds distinct and novel research programs with promising and transformative impact that will advance technology and sciences for the preservation of life, access to innovative solutions and a better understanding of the world we live in.

News Item New Terahertz Modulator Could Lead to More Advanced Medical and Security Imaging

Mona JarrahiA UCLA Henry Samueli School of Engineering and Applied Science research team has developed a breakthrough broadband modulator that could eventually lead to more advanced medical and security imaging systems.

Modulators manipulate the intensity of electromagnetic waves. For example, modulators in cell phones convert radio waves into digital signals that the devices can use and understand. In terahertz-based communication and imaging systems, they modify the intensity of terahertz waves.

Today's technologies take advantage of many parts of the electromagnetic spectrum — notably light waves and radio waves — but they rarely operate in the terahertz band, which lies between infrared and microwave on the spectrum.

Led by Mona Jarrahi, UCLA associate professor of electrical engineering, the group developed a terahertz modulator that performs across a wide range of the terahertz band with very high efficiency and signal clarity. Among the device’s advantages are that it could easily be incorporated into existing integrated circuit manufacturing processes, can operate at room temperature and does not require an external light source to operate.

The terahertz band has been the subject of extensive research, in large part because of its potential for medical imaging and chemical sensing technologies. For example, terahertz waves could be used to examine human tissue for signs for disease without damaging cells or the other health risks posed by X-rays. They also could be used in security screenings to penetrate fabric or plastics that conceal weapons.

Current optical modulators that use naturally existing materials, such as silicon or liquid crystals, to manipulate the intensity of light waves have proven to be very inefficient in terahertz frequencies. And modulators based on artificial materials, so-called metamaterials, thus far have a limited use because they only operate in a narrow band of the terahertz range.

The new modulator is based on an innovative artificial metasurface — a type of surface with unique properties that is defined by the geometry of its individual building blocks, and their arrangement. The metasurface developed by Jarrahi's team is composed of an array of micro-electromechanical units that can be opened and closed using electric voltage. Opening or closing the metasurface encodes the incoming terahertz wave into a corresponding series of zeroes or ones, which are then transformed into images.

"Our new metasurface broadens the realm of metamaterials to broadband operation for the first time, and it diminishes many of the fundamental physical constraints in routing and manipulating terahertz waves, especially in terahertz imaging and spectroscopy systems," Jarrahi said. "Our device geometry can switch from an array of microscale metallic islands to an array of interconnected metallic loops, altering its electromagnetic properties from a transparent surface to a reflecting surface, which manipulates the intensity of terahertz waves passing through over a broad range of frequencies."

The research was published July 16 in the journal Nature Scientific Reports.

The study's lead authors are Mehmet Unlu and Mohammed Reza Hashemi, who were postdoctoral scholars in Jarrahi's group when she was a member of the faculty at the University of Michigan. Other authors are Christopher Berry and Shenglin Li, former students in Jarrahi's group, and Shang Hua Yang, a current UCLA graduate student.

The research was funded by the National Science Foundation's Sensor and Sensing Systems Division and an Army Research Office Young Investigator award.

News Item Professor John Villasenor Provides Congressional Testimony Regarding Digital Media Distribution

John D. VillasenorOver the last fifteen years, there have been fundamental shifts in how consumers access media. Internet-based distribution is now the norm, and content providers are increasingly shifting to license-based models in which consumers are licensees as opposed to owners of copies of digital books, songs, and movies. This raises important questions regarding the role of copyright law in the digital media ecosystem.

On June 2, the House Judiciary Committee convened a hearing to consider some of these questions. Professor John Villasenor was asked to be a witness at the hearing, and provided testimony on how potential changes to copyright law would impact the media distribution landscape. His testimony also addressed the growing role of contract law in governing the permitted and prohibited uses of the books, songs, and movies obtained over the Internet.

News Item Magnetic Topological Insulators Developed at UCLA are 1,000 Times More Energy-Efficient for Switching
UCLA Engineering


Structure of the two-layer topological insulator developed by UCLA Engineering researchers.

Topological insulators are an emerging class of materials that act as both insulators and conductors, and could potentially be used in smartphones, computers and other electronic devices.

A research team at the UCLA Henry Samueli School of Engineering and Applied Science has developed a new class of topological insulators in which one of two layers is magnetized. The advance could lead to the development of much more energy-efficient big-data processing systems and ultra-low power electronics.

Led by Kang Wang, the Raytheon Professor of Electrical Engineering at UCLA and the study's principal investigator, the team demonstrated for the first time that the new topological insulators can be electrically "switched" to make them significantly more energy-efficient than current devices. The research was published April 28 in the journal Nature Materials.

"We are very excited about this important result with the new topological insulators, which should lead to the advancement of future low-power, green electronics," Wang said.

The interiors of topological insulators prevent the flow of electrical currents, but their surfaces allow a current to move with very little resistance. Perhaps most importantly, their surfaces enable the transport of spin-polarized electrons while preventing the "scattering" of electrons that causes energy to be dissipated and wasted.

The topological insulator created at UCLA comprises two layers, one of which contains chromium, a magnetic element. An electrical current that drives spin-polarized electrons can switch the up-down polarity of the magnetic chromium atoms. This switching is what enables the device to write memory or perform calculations.

Most significantly, the new two-layer structure uses 1,000 times less energy to switch polarity than comparable memory structures.

"This is the first time that topological insulators have been incorporated in a magnetic structure that can be efficiently switched, and is perhaps the first demonstration of potential applicable devices based on topological insulators," said Yabin Fan, the paper's lead author and a UCLA graduate student in electrical engineering. 

The study’s other authors include UCLA Engineering graduate students Pramey Upadhyaya and Xufeng Kou.

The research was supported by the Defense Advanced Research Projects Agency’s Mesodynamic Architectures program. Additional support came from two UCLA Engineering research centers, the Western Institute of Nanoelectronics and the center for Functional Accelerated nanoMaterial Engineering
