A Step Closer to Ultra Slim Mobile Phone
Professor Baek Kyung Wook (department of Material Science and Engineering) succeeded in developing an ultra-thin conjugation technique that can perfectly replace the modular contact in electronic devices.
The research team developed a compound material using ultra-fine solder-adhesive film and developed the vertical ultrasonic conjugation process thereby making a reliable utra-thin conjugation.
The developed technique allowed for very thin and reliable conjugation and will be able to replace the socket type connector and is expected to revolutionize the electronic device industry.
In mobile electronic devices like the smartphone, the trend is to incorporate various functional modules like camera, display, touchscreens, etc. in addition to striving for miniaturization of the device.
Recently the problem was the fact that the number of modules within the device was increasing due to the incorporation of various functions, and consequently the volume that these modules took up increased as well, which made miniaturization almost impossible.
Professor Baek‘s team succeeded in improving upon this problem by creating a compound material that has ultra-fine solder particles that can melt to form alloy fusion with the electrode and thermosetting adhesive film that can wrap around the electrode and provide mechanical protection.
The use of this material made it possible to reduce the thickness of the connector by hundredth fold which improved electrical, mechanical properties and highly reliable.
From a processing standpoint the conventional conjugation process involved heating the mechanical block and was therefore hard to manage its production and also consumed 1000W and took up to 15 seconds.
By contrast, Professor Baek’s team’s new process uses only ultrasound to locally heat and melt the conjugation point itself thereby reducing power consumption to 100W and conjugation time to 1~5 seconds.
The technique developed by Professor Baek and Lee Ki Won Doctorate student was awarded Excellent Dissertation Award by world famous journals like the Electronic Components and Technology Conference and is being recognized worldwide.

A Light Weight, Energy Effcient Household Polysomnography (PSG) System Developed
A smart ‘household polysomnography (PSG) system’ was developed by domestic research team.
Professor Yoo Hui Joon and his research team of KAIST’s department of Electricity and Electronic Engineering successfully developed a PSG system that is light weight and has high performance levels. The conventional PSG systems were complex with numerous lines and wires.
The PSG is used to monitor biological signals during sleep and the monitored results are used to diagnose and cure sleep-related illnesses and disorders. However because of restrictions like the size of the machine, impurities, and the change in environment, multiple trials over several days were required to obtain accurate data.
The system developed by the research team is lighter than a q-tip so as to not disturb the patient’s sleep. It also has Intelligent Circuit (IC) that detects when sensors come detached and automatically replaces the sensor with another sensor thereby allowing continual monitoring of the user.
A low-power consuming circuit was implemented allowing the entire system to run continuously on a single coin battery for 10 hours which effectively decreased the weight of the system and simultaneously allows for uninterrupted monitoring of the user over the entire sleep cycle.
Even a remote diagnosis system can be implemented. The user will don the PSG and sleep at home, ensuring that a normal heat beat rate, brain waves, breathing, etc. will be monitored. The data procured overnight can be sent to the experts online who will be able to diagnose remotely.
The research team plans on performing research in cooperation with the KAIST hospital and U-Healthcare research.
The research result is winning worldwide rave. The system was announced in the International Solid-State Circuits Conference (ISSCC) and was published in ISSCC magazine and in Japan’s NIKKEI Electronics January edition.

Master of Science in Intellectual Property: First Class Starts on Saturday, February 6, 2010
Newly Established, Postgraduate Course for Master of Science in Intellectual Property
First class starts on February 6th, 2010
In conjunction with Korean Intellectual Property Office (KIPO), KAIST has established a new postgraduate course for a master of science in intellectual property (IP). 41 students have enrolled the course, and its first class will begin February 6th, 2010. With a diverse professional background, the first-year students came from private businesses, IP service industry, and public organizations.
Globally well-known companies—Samsung Electronics, LG Electronics, and the Pohang Iron and Steel Company (POSCO)—and mid-sized companies have offered scholarships to support the new M.S. Program. Business and industry in Korea have recognized the increasingly important role of intellectual property in a modern economy and showed a strong interest in developing workforce specialized in subjects such as, but not limited to, patent law, copyright and designs law, trade mark law, unfair competition, anti-trust law, competition law, and trade secret law.
Prosecutor Chan-Gi Na from Seoul Central District Prosecutor’s Office said, “I’ve applied for the master program at KAIST because I wanted to learn more about intellectual property in greater depth. Through the coursework, I hope to enhance my knowledge on the subjects and use it for the protection of Koreans’ IP related rights and the development of our nation’s IP industry.”
Assistant Manager Jin-Hong Bae from Samsung Securities, Inc. said, “Since the capital market law becomes effective, the need for developing new financial products or services in our finance market has rapidly grown. We no longer can make our financial products by simply copying or ripping off ideas from others. It’s a must practice, not an option, to set up a system under which we are able to protect our IPs.”
“I would like to become an expert in our finance market, who really knows how to commercialize intellectual property assets into benefits, so any know-hows or ideas accumulated from years of working in the field can be registered and protected,” added Mr. Bae.
KAIST’s Mater Program for intellectual property is designed for engineers who wish to acquire the skills required to play a leading role in the field. These engineers, KAIST anticipates, will establish and execute business strategies to protect intellectual property, generate added values for a company, and effectively respond against patent related claims.
The intellectual property will seize up to 90% of business values to be generated in the 21st century. KAIST has long foreseen the need for training top-notch engineers in intellectual property. Combined with multidisciplinary approach to engineering, law, and management, the new M.S. Program will provide students with a variety form of classes to assist them in getting a practical knowledge as needed based on their interests and career aspirations. Examples of the classes are workshops on the change in technology trends—i.e., information technology (IT), environmental technology (ET), and bio technology (BT); standardization of intellectual property and value assessment; and patent law related claims.
“All professors involved in the course are experts who are equipped with hands-on experiences in working on intellectual property for a long time at government agencies, companies, and law firms,” Professor Chul-Ho Kim, responsible for overseeing the entire program, said.
He also expressed his confidence that “We have set up an academic system to induct highly qualified professionals and engineers, capable of handling all aspects of intellectual property related issues, into work places. Our coursework encompasses technology, research and development (R&D), and management, and students who complete the program will be ready to tackle down any intellectual property matters in the 21st century.”
Freshmen convocation for the IP M.S. Program is scheduled on February 20th at KAIST, and President Nam Pyo Suh and Commissioner Jung-Sik Koh of Korean Intellectual Property (KIPO) will attend the event.
