Aqueous storage device can be charged in less than half a minute
A KAIST research team developed a new hybrid energy storage device that can be charged in less than half a minute. It employs aqueous electrolytes instead of flammable organic solvents, so it is both environmentally friendly and safe. It also facilitates a boosting charge with high energy density, which makes it suitable for portable electronic devices.
Breath sensor to spot diseases and monitor health
Breath pattern recognition is a futuristic diagnostic platform. Simple characterising target gas concentrations of human exhaled breath will lead to diagnose of the disease as well as physical condition. A research group under Prof. Il-Doo Kim in the Department of Materials Science has developed diagnostic sensors using protein-encapsulated nanocatalysts, which can diagnose certain diseases by analysing human exhaled breath.
Thin-film transistors developed for wearable display
With the advent of the IoT era, strong demand has grown for wearable and transparent displays that can be applied to various fields such as augmented reality (AR) and skin-like thin flexible devices. However, previous flexible transparent displays have posed real challenges to overcome, which are, among others, poor transparency and low electrical performance.
Graphene-based electrodes for efficient flexible OLEDS
A Korean research team led by Professor Seunghyup Yoo from the School of Electrical Engineering, KAIST and Professor Tae-Woo Lee from the Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH) has developed highly flexible OLEDs with excellent efficiency by using graphene as a transparent electrode (TE) which is placed in between titanium dioxide (TiO2) and conducting polymer layers. The research re...

Fireflies inspire the improvement of OLEDs
Researchers have investigated the optical properties of the firefly's light-emitting cuticle, which is not smooth like most human-made lights, but instead is patterned with tiny hierarchical structures. Inspired by these features, the researchers replicated the patterns to create a bioinspired OLED, resulting in a 60% increase in the light extraction efficiency and 15% wider angle of illumination.
Technology enables unzipping of the graphene plane
A research team at Korea Advanced Institute of Science and Technology (KAIST) has developed a technique that enables unzipping of the graphene plane without uncontrollable damage. Professor Sang-Wook Kim's research team of KASIT's Material Science and Engineering Department has developed a technique, which enables unzipping of the graphene plane without uncontrollable damage. The research findings were published online on the 22th January issue o...
Biosniffers diagnose diseases via biomarkers in breath
Professor Il-Doo Kim in the Department of Materials Science and Engineering at Korea Advanced Institute of Science and Technology (KAIST) is developing ultrasensitive and highly selective gas sensors to diagnose diseases by exhaled breath analysis. Professor Kim has led the development of semiconductor metal oxide-based nanofiber sensor arrays, which are optimised for pattern recognition of breath prints.
Development of a wall-climbing drone
A new wall-climbing drone can approach any type of structure by flying and sticking to the target and utitlising a pose change and perching mechanism. The integrity of large structures like bridges, high-rise buildings, wind turbines, and large aircrafts is deeply related with security. Nowadays, due to the aging of large structures and the potential concerns about their collapse, interest in structural health monitoring has risen all over the wo...
Micro modular reactor is cooled by supercritical S-CO2
A research team at Korea Advanced Institute of Science and Technology (KAIST) (Prof. Jeong Ik Lee, Prof. Yonghee Kim, and Prof. Yong Hoon Jeong) has suggested an innovative concept of a reactor cooled by supercritical state carbon dioxide (S-CO2). The core has long life (20 years) without refueling as well as inherent safety features. The S-CO2 Brayton cycle was proposed as a power conversion system to achieve a compact and lightweight module.
Non-natural biomedical polymers produced from microorganisms
Renewable non-food biomass could potentially replace petrochemical raw materials to produce energy sources, useful chemicals, or a vast array of petroleum-based end products such as plastics, lubricants, paints, fertilizers, and vitamin capsules. In recent years, biorefineries which transform non-edible biomass into fuel, heat, power, chemicals, and materials have received a great deal of attention as a sustainable alternative to decreasing the r...
Smart glasses offer a keyboard to type text
K-Glass, smart glasses reinforced with AR that were first developed by the Korea Advanced Institute of Science and Technology (KAIST) in 2014, with the second version released in 2015, is back with an even stronger model. The latest version, which KAIST researchers are calling K-Glass 3, allows users to text a message or type in key words for Internet surfing by offering a virtual keyboard for text and even one for a piano.
Fireproof Aerial Robot System: a new application for drones
Among the most exciting firefighting innovations is the Fireproof Aerial Robot System (FAROS), which has been developed by a research team at the Korea Advanced Institute of Science and Technology. Designed specifically to help detect and combat fires in high-rise buildings, the drone can both fly and climb walls, using technology that was first developed for a previous model called the Climbing Aerial Robot System (CAROS).
Fibre-like LED can be applied in wearable displays
Professor Kyung-Cheol Choi and his research team from the School of Electrical Engineering at KAIST have developed fibre-like LEDs, which can be applied in wearable displays. The research findings were published online in the July 14th issue of Advanced Electronic Materials. Traditional wearable displays were manufactured on a hard substrate, which was later attached to the surface of clothes.
KAIST's wireless Online Electric Vehicle
The Online Electric Vehicle (OLEV), developed by the Korea Advanced Institute of Science and Technology (KAIST), is an electric vehicle that can be charged while stationary or driving, thus removing the need to stop at a charging station. Likewise, an OLEV tram does not require pantographs to feed power from electric wires strung above the tram route.
