KAST Opened the Campus to the Public
KAIST hosted OPEN KAIST 2017 on the main campus from November 2 to 3, 2017. OPEN KAIST is a science and cultural event designed for students and the general public to experience and take a glance at research labs. More than 10,000 visitors came to KAIST this year. Groups of families and students came to KAIST to experience various programs related to science. Twenty departments, including Mechanical Engineering, Aerospace Engineering, the Graduate School of Cultural Technology, and Materials Science and Engineering participated in the event, along with three research centers and the Public Relations Office. The event was composed of a total of 70 programs in four sections: lab tour, research performance exhibition, department introduction, and special lectures. The kick off activity for the event was a trial game of the AI World Cup 2017 which will be hosted by KAIST in December 2017. Many people also visited the mobile health care showroom where they could experience what a future smart home and hospital would look like. It was also interesting to visit a futuristic living space for one-person households that provides virtual reality services. KAIST hopes that the event offers an opportunity for children and students to get to know about science better. Professor Jong-Hwan Kim, the Dean of the College of Engineering at KAIST said, “OPEN KAIST is the one and only opportunity to visit and experience our research labs. KAIST will make every effort to take a step closer to the public by focusing on research that contributes to human society.”
KAIST Develops Subminiature, Power-Efficient Air Pollution Sensing Probe
Professor Inkyu Park and his research team from the Department of Mechanical Engineering at KAIST have developed a subminiature, power-efficient air-pollution sensing probe that can be applied to mobile devices. Their research findings were published online in the January 30th issue of Scientific Reports. As air pollution has increased, people have taken greater interest in health care. The developed technology could allow people to measure independently the air pollution level of their surrounding environments. Previous instruments used to measure air pollution levels were bulky and consumed a lot of power. They also often produced inaccurate results when measuring air pollution in which different toxic gases were mixed. These problems could not be resolved with existing semiconductor manufacturing process. Using local temperature field control technology, Professor Park’s team succeeded in integrating multiple heterogeneous nanomaterials and fitting them onto a small, low-power electronic chip. This microheating sensor can heat microscale regions through local hydrothermal synthesis. Because it requires a miniscale amount of nanomaterials to manufacture, the sensor is most suitable for mobile devices. Professor Park said, “Our research will contribute to the development of convergence technology in such field as air pollution sensing probes, biosensors, electronic devices, and displays.” The team's research was supported by the Ministry of Education and the Ministry of Science, ICT and Future Planning, Republic of Korea.
