Leon Chua, the founder of the circuit theory called "memristor," gave a talk at KAIST
Dr. Leon Ong Chua is a circuit theorist and professor in the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley. He visited KAIST on April 16, 2014 and gave a talk entitled “Memristor: New Device with Intelligence.”
Dr. Chua contributed to the development of nonlinear circuit theory and cellular neural networks (CNN). He was also the first to conceive of memristor which combines the characteristics of memory and resistor. Memristor is a type of resistor, remembering the direction and charge of electrical current that has previously flowed through the resistor. In other words, memristor can retain memory without power. Today, memristor is regarded as the fourth fundamental circuit element, together with capacitors, inductors, and resistors.
In 2008, researchers at Hewlett-Packard (HP) Labs developed the first working model of memristor, which was reported in Nature (May 1st , 2008).
In addition, Dr. Chua is an IEEE fellow and has received numerous awards including the IEEE Kirchhoff Award, the IEEE Neural Network Pioneer Award, the IEEE Third Millennium Medal, and the Top 15 Most Cited Author in Engineering Award.

Thermoelectric generator on glass fabric for wearable electronic devices
Wearable computers or devices have been hailed as the next generation of mobile electronic gadgets, from smart watches to smart glasses to smart pacemakers. For electronics to be worn by a user, they must be light, flexible, and equipped with a power source, which could be a portable, long-lasting battery or no battery at all but a generator. How to supply power in a stable and reliable manner is one of the most critical issues to commercialize wearable devices.
A team of KAIST researchers headed by Byung Jin Cho, a professor of electrical engineering, proposed a solution to this problem by developing a glass fabric-based thermoelectric (TE) generator that is extremely light and flexible and produces electricity from the heat of the human body. In fact, it is so flexible that the allowable bending radius of the generator is as low as 20 mm. There are no changes in performance even if the generator bends upward and downward for up to 120 cycles.
To date, two types of TE generators have been developed based either on organic or inorganic materials. The organic-based TE generators use polymers that are highly flexible and compatible with human skin, ideal for wearable electronics. The polymers, however, have a low power output. Inorganic-based TE generators produce a high electrical energy, but they are heavy, rigid, and bulky.
Professor Cho came up with a new concept and design technique to build a flexible TE generator that minimizes thermal energy loss but maximizes power output. His team synthesized liquid-like pastes of n-type (Bi2Te3) and p-type (Sb2Te3) TE materials and printed them onto a glass fabric by applying a screen printing technique. The pastes permeated through the meshes of the fabric and formed films of TE materials in a range of thickness of several hundreds of microns. As a result, hundreds of TE material dots (in combination of n and p types) were printed and well arranged on a specific area of the glass fabric.
Professor Cho explained that his TE generator has a self-sustaining structure, eliminating thick external substrates (usually made of ceramic or alumina) that hold inorganic TE materials. These substrates have taken away a great portion of thermal energy, a serious setback which causes low output power.
He also commented,
"For our case, the glass fabric itself serves as the upper and lower substrates of a TE generator, keeping the inorganic TE materials in between. This is quite a revolutionary approach to design a generator. In so doing, we were able to significantly reduce the weight of our generator (~0.13g/cm2), which is an essential element for wearable electronics."
When using KAIST's TE generator (with a size of 10 cm x 10 cm) for a wearable wristband device, it will produce around 40 mW electric power based on the temperature difference of 31 °F between human skin and the surrounding air.
Professor Cho further described about the merits of the new generator:
"Our technology presents an easy and simple way of fabricating an extremely flexible, light, and high-performance TE generator. We expect that this technology will find further applications in scale-up systems such as automobiles, factories, aircrafts, and vessels where we see abundant thermal energy being wasted."
This research result was published online in the March 14th issue of Energy & Environmental Science and was entitled "Wearable Thermoelectric Generator Fabricated on Glass Fabric."

Festival Featuring Asia's Best Science Students to be Held
The first Electronic Olympics, which will host students from five top Asian research-centered universities, will be held in August at KAIST. Students will take part in competitive events and explore cultural diversity. Student representatives of HKUST, NTU, TITECH, Tsinghua University, and KAIST gathered on February 20 to begin planning the tentatively named “ASPIRE E-Olympics.”
The key words of this Olympics are "Harmony" and "Competition." The events will be composed of an AI programming contest, SEM (Scanning Electron Microscope) picture contest, and the other technology-based contests. Cultural events, where each university’s students can interact, will also be prepared.
ASPIRE (Asian Science and Technology Pioneering Institutes of Research and Education) events have been held from 2009. Previously, the ASPIRE forum has been an exchange event for groups of vice presidents and graduate school students from the five schools to exchange achievements in education and research. This year, it has been extended to undergraduates.
Yoseop Kim, KAIST’s student body vice president, said that he wants to make a MOU with some of Asia’s best research-centered universities and develop it into something similar to the Davos Forum. His intention is to support the E-Olympics in the hope that ASPIRE will become a top university consortium.

KAIST President Held One-year Anniversary Press Conference
President Steve Kang had a press conference
on February 25, 2014 at the Faculty Club on campus, commemorating the first
year of his presidency. About 30 different media representatives nationwide
attended the meeting.
At his first press conference on the anniversary of his tenure, President Kang
described what he has achieved in the past year, which were: 1) rebuilding the
campus culture to start a campaign for mutual respect, trust, and open
communication by holding meetings with the members of the KAIST community more
than 60 times, 2) establishing core values, creativity and challenge, to
enhance the fabric of the community, 3) restructuring of the university
administration, and 4) the announcement of the mid- and long-term development
plan.
He also mentioned that “2014 will be another exciting year for KAIST to make
more progress” and laid out a few major projects to be implemented this year:
launching of the “Committee for Engineering Education Innovation,” “Startup
KAIST” (an entrepreneurship program), “Greater Collaboration in Technology
Translation and Management with Seoul National University,” and “KAIST End Run”
(a global business incubation program).Explanation of 2014 Major Endeavors by President KangFor
the past decade, domestic engineering schools weighed SCI dissertation
publication more heavily in university evaluations, yielding a world-class
research level. However, such an approach resulted in placing less importance
on entrepreneurship, commercialization, or creating economic values.As a
result, engineering Professors have been evaluated as being too focused on theoretical
SCI dissertation research rather than practical research that could yield
economic benefits through commercialization of developed technology. In
addition, some have criticized that engineering universities have not educated
creative researchers demanded by the industry.KAIST
has begun responding to these criticisms and has made a few suggestions to strengthen
engineering education, promote entrepreneurship in engineers, and globalize Korean
venture companies.As
part of such efforts, KAIST established the KAIST Education and Research
Innovation Committee, composed of various individuals from the industry,
research institutes, alumni, faculty members, and others, to discuss ways to reinforce
engineering education.
A
course to encourage entrepreneurship will be implemented.Startup
KAIST will develop and commercialize innovative ideas from members of KAIST, and
the End Run project will enable students and faculty to establish a global,
venture company. KAIST hopes that a new entrepreneurial culture will be created
on campus, thereby the research success of KAIST members will lead to commercialization
and startups.KAIST
plans on releasing free internet lectures as part of its knowledge contribution
and sponsoring programs which will level the playing field in eduation.KAIST
will establish the KAIST Open Online Course (KOOC). An entrepreneurship
curriculum will be developed for KOOC. KAIST will start trials for KOOC from
2015, gradually expanding to include more courses.

KAIST developed an extremely low-powered, high-performance head-mounted display embedding an augmented reality chip
Walking around the streets searching for a place to eat will be no hassle when a head-mounted display (HMD) becomes affordable and ubiquitous. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) developed K-Glass, a wearable, hands-free HMD that enables users to find restaurants while checking out their menus. If the user of K-Glass walks up to a restaurant and looks at the name of the restaurant, today’s menu and a 3D image of food pop up. The Glass can even show the number of tables available inside the restaurant. K-Glass makes this possible because of its built-in augmented reality (AR) processor. Unlike virtual reality which replaces the real world with a computer-simulated environment, AR incorporates digital data generated by the computer into the reality of a user. With the computer-made sensory inputs such as sound, video, graphics or GPS data, the user’s real and physical world becomes live and interactive. Augmentation takes place in real-time and in semantic context with surrounding environments, such as a menu list overlain on the signboard of a restaurant when the user passes by it, not an airplane flight schedule, which is irrelevant information, displayed. Most commonly, location-based or computer-vision services are used in order to generate AR effects. Location-based services activate motion sensors to identify the user’s surroundings, whereas computer-vision uses algorithms such as facial, pattern, and optical character recognition, or object and motion tracking to distinguish images and objects. Many of the current HMDs deliver augmented reality experiences employing location-based services by scanning the markers or barcodes printed on the back of objects. The AR system tracks the codes or markers to identify objects and then align them with virtual reality. However, this AR algorithm is difficult to use for the objects or spaces which do not have barcodes, QR codes, or markers, particularly those in outdoor environments and thus cannot be recognized. To solve this problem, Hoi-Jun Yoo, Professor of Electrical Engineering at KAIST and his team developed, for the first time in the world, an AR chip that works just like human vision. This processor is based on the Visual Attention Model (VAM) that duplicates the ability of human brain to process visual data. VAM, almost unconsciously or automatically, disentangles the most salient and relevant information about the environment in which human vision operates, thereby eliminating unnecessary data unless they must be processed. In return, the processor can dramatically speed up the computation of complex AR algorithms. The AR processor has a data processing network similar to that of a human brain’s central nervous system. When the human brain perceives visual data, different sets of neurons, all connected, work concurrently on each fragment of a decision-making process; one group’s work is relayed to other group of neurons for the next round of the process, which continues until a set of decider neurons determines the character of the data. Likewise, the artificial neural network allows parallel data processing, alleviating data congestion and reducing power consumption significantly. KAIST’s AR processor, which is produced using the 65 nm (nanometers) manufacturing process with the area of 32 mm2, delivers 1.22 TOPS (tera-operations per second) peak performance when running at 250 MHz and consumes 778 miliWatts on a 1.2V power supply. The ultra-low power processor shows 1.57 TOPS/W high efficiency rate of energy consumption under the real-time operation of 30fps/720p video camera, a 76% improvement in power conservation over other devices. The HMDs, available on the market including the Project Glass whose battery lasts only for two hours, have revealed so far poor performance. Professor Yoo said, “Our processor can work for long hours without sacrificing K-Glass’s high performance, an ideal mobile gadget or wearable computer, which users can wear for almost the whole day.” He further commented:“HMDs will become the next mobile device, eventually taking over smartphones. Their markets have been growing fast, and it’s really a matter of time before mobile users will eventually embrace an optical see-through HMD as part of their daily use. Through augmented reality, we will have richer, deeper, and more powerful reality in all aspects of our life from education, business, and entertainment to art and culture.” The KAIST team presented a research paper at the International Solid-State Circuits Conference (ISSCC) held on February 9-13, 2014 in San Francisco, CA, which is entitled “1.22TOPS and 1.52mW/MHz Augmented Reality Multi-Core Processor with Neural Network NoC for HMD Applications.”Youtube Link: http://www.youtube.com/watch?v=wSqY30FOu2s&feature=c4-overview&list=UUirZA3OFhxP4YFreIJkTtXw
