Core technologies for the construction of small-diameter utility tunnels in urban environments   The KAIST Center for Utility Tunnel (CUT) developed core design and construction technologies for small-diameter utility tunnels in urban environments that contribute to the safe and economic underground construction. A full-scale performance verification facility was established to test the performance of the de...

Small Deformable Ceramics   Unlike the general belief that ceramics are hard and brittle, they become very deformable when cut into nano-sized pieces. Dahye Shin and Dongchan Jang in the NQe department discovered the physical origin of this unusual flexibility in ceramics and demonstrated that it can be used to tune the mechanical responses of otherwise brittle materials.   Article | Spring 2021 &n...

WIKA: A Projected Augmented Reality Workbench for Interactive Kinetic Art (IKA)   WIKA is a projected AR workbench that allows non-experts to create IKA in the form of a layered picture frame (IKPF). It supports STEAM education through an iterative prototyping including design, programming, simulation, and making in a single workspace.   Article | Spring 2021     Interactive kinetic art (...

Multi-agent reinforcement learning for mission planning of a communication-aware multi-UAV system   The research focused on a multi-target sensing mission operated by the autonomous multi-UAV system under the air-to-ground and air-to-air communication channel models. A multi-agent reinforcement learning technique is applied to obtain a distributed real-time mission planning algorithm.   Article | Sp...

Novel transparent neurotool compatible with light   Optogenetics allows us to control neuronal activities using light with high spatial and temporal resolution. However, the light affects not only the neurons, but also the electrodes that are used to record the neural signals, generating noise signals called photoelectric artifacts. For accurate recording without photoelectric artifacts, a KAIST joi...

Industrial-level production of bio-succinic acid from a renewable resource using a metabolically-engineered microorganism   A research group led by Professor Sang Yup Lee has developed a bioprocess employing a metabolically-engineered microorganism that allows industrial-level production of bio-succinic acid from a renewable resource. Succinic acid serves as a precursor for industrial chemicals and biodegrada...
