KAIST Made Great Improvements of Nanogenerator Power Efficiency The energy efficiency of a piezoelectric nanogenerator developed by KAIST has increased by almost 40 times, one step closer toward the commercialization of flexible energy harvesters that can supply power infinitely to wearable, implantable electronic devices. NANOGENERATORS are innovative self-powered energy harvesters that convert kinetic energy created from vibrational and mechanical sources into electrical power, removing the need of external circuits or batteries for electronic devices. This innovation is vital in realizing sustainable energy generation in isolated, inaccessible, or indoor environments and even in the human body. Nanogenerators, a flexible and lightweight energy harvester on a plastic substrate, can scavenge energy from the extremely tiny movements of natural resources and human body such as wind, water flow, heartbeats, and diaphragm and respiration activities to generate electrical signals. The generators are not only self-powered, flexible devices but also can provide permanent power sources to implantable biomedical devices, including cardiac pacemakers and deep brain stimulators. However, poor energy efficiency and a complex fabrication process have posed challenges to the commercialization of nanogenerators. Keon Jae Lee, Associate Professor of Materials Science and Engineering at KAIST, and his colleagues have recently proposed a solution by developing a robust technique to transfer a high-quality piezoelectric thin film from bulk sapphire substrates to plastic substrates using laser lift-off (LLO). Applying the inorganic-based laser lift-off (LLO) process, the research team produced a large-area PZT thin film nanogenerators on flexible substrates (2cm x 2cm). “We were able to convert a high-output performance of ~250 V from the slight mechanical deformation of a single thin plastic substrate. Such output power is just enough to turn on 100 LED lights,” Keon Jae Lee explained. The self-powered nanogenerators can also work with finger and foot motions. For example, under the irregular and slight bending motions of a human finger, the measured current signals had a high electric power of ~8.7 μA. In addition, the piezoelectric nanogenerator has world-record power conversion efficiency, almost 40 times higher than previously reported similar research results, solving the drawbacks related to the fabrication complexity and low energy efficiency. Lee further commented, “Building on this concept, it is highly expected that tiny mechanical motions, including human body movements of muscle contraction and relaxation, can be readily converted into electrical energy and, furthermore, acted as eternal power sources.” The research team is currently studying a method to build three-dimensional stacking of flexible piezoelectric thin films to enhance output power, as well as conducting a clinical experiment with a flexible nanogenerator. This research result, entitled “Highly-efficient, Flexible Piezoelectric PZT Thin Film Nanogenerator on Plastic Substrates,” was published as the cover article of the April issue of Advanced Materials.

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."

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.
