Award Winning Portable Sound Camera Design
- A member of KAIST’s faculty has won the “Red Dot Design Award,” one of three of the most prestigious design competitions in the world, for the portable sound camera. KAIST’s Industrial Design Professor Suk-Hyung Bae’s portable sound camera design, made by SM Instruments and Hyundai, has received a “Red Dot Design Award: Product Design,” one of the most prestigious design competitions in the world. If you are a driver, you must have experienced unexplained noises in your car. Most industrial products, including cars, may produce abnormal noises caused by an error in design or worn-out machinery. However, it is difficult to identify the exact location of the sound with ears alone. This is where the sound camera comes in. Just as thermal detector cameras show the distribution of temperature, sound cameras use a microphone arrangement to express the distribution of sound and to find the location of the sound. However, existing sound cameras are not only too big and heavy, their assembly and installation are complex and must be fixed on a tripod. These limitations made it impossible to measure noises from small areas or the base of cars. The newly developed product is an all-in-one system resolving the inconvenience of assembling the microphone before taking measurements. Moreover, the handle in the middle is ergonomically designed so users can balance its weight with one hand. The two handles on the sides work as a support and enable the user to hold the camera in various ways. At the award ceremony, Professor Suk-Hyung Bae commented, “The effective combination of cutting edge technology and design components has been recognized.” He also said, “It shows the competency of the KAIST’s Department of Industrial Design, which has a high understanding of science and technology.” On the other hand, SM Instruments is a sound vibration specialist company which got its start from KAIST’s Technology Business Incubation Centre in 2006 and earned its independence by gaining proprietary technology in only two years. SM Instruments is contributing to developing national sound and vibration technology through relentless change and innovation. ; Figure 1: Red Dot Design Award winning the portable sound camera, SeeSV-S205 Figure 2: Identifying the location of the noise using the portable sound camera Figure 3: The image showing the sound distribution using the portable sound camera
KAIST Develops Wireless Power Transfer Technology for High Capacity Transit
KAIST and the Korea Railroad Research Institute (KRRI) have developed a wireless power transfer technology that can be applied to high capacity transportation systems such as railways, harbor freight, and airport transportation and logistics. The technology supplies 60 kHz and 180 kW of power remotely to transport vehicles at a stable, constant rate. KAIST and KRRI successfully showcased the wireless power transfer technology to the public on February 13, 2013 by testing it on the railroad tracks at Osong Station in Korea. Originally, this technology was developed as part of an electric vehicle system introduced by KAIST in 2011 known as the On-line Electric Vehicle (OLEV). OLEV does not need to be parked at a charging station to have a fully powered battery. It gets charged while running, idling, and parking, enabling a reduction in size of the reserve battery down to one-fifth of the battery on board a regular electric car. The initial models of OLEV, a bus and a tram, receive 20 kHz and 100 kW power at an 85% transmission efficiency rate while maintaining a 20cm air gap between the underbody of vehicle and the road surface. OLEV complies with the national and international standards of 62.5 mG, a safety net for electromagnetic fields. In July 2013, for the first time since its development, OLEV will run on a regular road, an inner city route in the city of Gumi, requiring 40 minutes of driving each way. Today’s technology demonstration offers further support that OLEV can be utilized for large-scale systems. Professor Dong-Ho Cho, Director of Center for Wireless Power Transfer Technology Business Development at KAIST, explained the recent improvements to OLEV: “We have greatly improved the OLEV technology from the early development stage by increasing its power transmission density by more than three times. The size and weight of the power pickup modules have been reduced as well. We were able to cut down the production costs for major OLEV components, the power supply, and the pickup system, and in turn, OLEV is one step closer to being commercialized.” If trains receive power wirelessly, the costs of railway wear and tear will be dramatically reduced. There will be no power rails, including electrical poles, required for the establishment of a railway system, and accordingly, lesser space will be needed. Tunnels will be built on a smaller scale, lowering construction costs. In addition, it will be helpful to overcome major obstacles that discourage the construction of high speed railway systems such as noise levels and problems in connecting pantograph and power rails. KAIST and KRRI plan to apply the wireless power transfer technology to trams in May and high speed trains in September.

KAIST hosts the first Can Satellite (Cansat) competition
Figure: The cansat is sent up into the air using a balloon and then separated at a certain height. The cansat slowly descends and sends terrestrial observation or atmospheric information back to earth. KAIST will host the first ever Cansat Competition Korea, in which students from different age groups can participate in building and testing the performance of their custom satellites. The Satellite Technology Research Center (SaTReC) at KAIST announced that it will take applications for the Cansat Competition Korea until May 25th. A cansat is a can-sized educational satellite that contains the basic elements of a real satellite. It is fired up to a few hundred meters in the air using balloons or small rockets and then separated like a real satellite, collecting data and sending the information back to earth. Cansat competitions are regularly held in the United States or Europe, where they have advanced space development programs, but this is the first time this competition will be held in Korea. The competition caters to different age groups through a cansat experience science camp for elementary and middle school students and a cansat competition for high school and college students. The science camp will be held from August 7th to 9th at KAIST and Sejong City and will include satellite education, visits to space development centers (KAIST Satellite Technology Research Center and the Korea Aerospace Research Institute), hand-on experience with basic cansat kits, and other various programs. The science camp will consist of a maximum of 20 teams comprised of students from fifth to ninth grade. Each team will have an advisory teacher and 3 to 4 students and can apply for the competition at no cost. The cansat competition will test high school and college students on their personally designed and built can satellites along with the creativity of their mission and developmental outcome. The preliminary review will choose a maximum of 15 teams, while the secondary review will select the 5 teams that will make the final competition based on their design presentation. On August 9th, these 5 teams will be evaluated on their technical ability, mission capacity and presentation skills.

Biomimetic reflective display technology developed
Professor Shin Jung Hoon The bright colors of a rainbow or a peacock are produced by the reflection and interference of light in transparent periodic structures, producing what is called a structural color. These colors are very bright and change according to the viewing angle. On the other hand, the wings of a morpho-butterfly also have structural colors but are predominantly blue over a wide range of angles. This is because the unique structure of the morpho-butterfly’s wings contains both order and chaos. Professor Shin Jung Hoon’s team from the Department of Physics and the Graduate School of Nanoscience and Technology at KAIST produced a display that mimics the structure of the morpho-butterfly’s wings using glass beads. This research successfully produced a reflective display (one that reflects external light to project images), which could be used to make very bright displays with low energy consumption. This technology can also be used to make anti-counterfeit bills, as well as coating materials for mobile phones and wallets. The structure of the morpho-butterfly’s wings seems to be in periodic order at the 1-micrometer level, but contains disorder at the 100-nanometer level. So far, no one had succeeded in reproducing a structure with both order and disorder at the nanometer level. Professor Shin’s team randomly aligned differently sized glass beads of a few hundred nanometers to create chaos and placed a thin periodic film on top of it using the semiconductor deposition method, thereby creating the morpho-butterfly-like structure over a large area. This new development produced better color and brightness than the morpho-butterfly wing and even exhibited less color change according to angle. The team sealed the film in thin plastic, which helped to maintain the superior properties whilst making it more firm and paper-like. Professor Shin emphasized that the results were an exemplary success in the field of biomimetics and that structural colors could have other applications in sensors and fashion, for example. The results were first introduced on May 3rd in Nature as one of the Research Highlights and will be published in the online version of the material science magazine, Advanced Materials. This research was jointly conducted by Professor Shin Jung Hoon (Department of Physics / Graduate School of Nanoscience and Technology at KAIST), Professor Park NamKyoo (Department of Electrical and Computer Engineering at Seoul National University), and Samsung Advanced Institute of Technology. The funding was provided by the National Research Foundation of Korea and the Ministry of Education, Science and Technology as part of the World Class University (WCU) project. Figure 2.

The output of terahertz waves enhanced by KAIST team
KAIST researchers have greatly improved the output of terahertz waves, the blue ocean of the optics world. This technology is expected to be applied to portable X-ray cameras, small bio-diagnostic systems, and in many other devices. Professor Ki-Hun Jeong"s research team from the Department of Bio and Brain Engineering used optical nano-antenna technology to increase the output of terahertz waves by three times. Terahertz waves are electromagnetic waves with frequencies between 100GHz to 30THz. They are produced when a femtosecond (10^-15 s) pulse laser is shone on a semiconductor substrate with photoconduction antennas, causing a photocurrent pulse of one picosecond (10^-12 s). Their long wavelengths, in comparison to visible light and infrared rays, give terahertz waves a high penetration power with less energy than X-rays, making them less harmful to humans. These qualities allow us to see through objects, just as X-rays do, but because terahertz waves absorb certain frequencies, we can detect hidden explosives or drugs, which was not possible with X-rays. We can even identify fake drugs. Furthermore, using the spectral information, we can analyze a material"s innate qualities without chemical processing, making it possible to identify skin diseases without harming the body. However, the output was not sufficient to be used in biosensors and other applications. Prof. Jeong"s team added optical nano-antennas, made from gold nano-rods, in between the photoconduction antennas and optimized the structure. This resulted in nanoplasmonic resonance in the photoconduction substrate, increasing the degree of integration of the photocurrent pulse and resulting in a three times larger output. Hence, it is not only possible to see through objects more clearly, but it is also possible to analyze components without a biopsy. Professor Jeong explained, "This technology, coupled with the miniaturization of terahertz devices, can be applied to endoscopes to detect early epithelial cancer" and that he will focus on creating and commercializing these biosensor systems. This research was published in the March issue of the international nanotechnology journal ACS Nano and was funded by the Korea Evaluation Institute of Industrial Technology and the National Research Foundation of Korea.
