Piezoelectric material can convert external pressure to electricity. If force is applied, the charges are separated into plus and minus charges, and due to the change in charge density, electricity flows. With the appropriate material, electricity can be produced efficiently, by applying it to humans, roads, or windmills to utilize movement and vibration. However, the problems were that the materials needed to create these elements were toxic, jeopardizing researchers’ health and the environment. They are also expensive.Professor Kim Jin-kon (CE), Sandip Maiti (CE, Ph.D), and Professor Khatua

▲ Kim Min-kyung (left), Prof. Rho Jun-sukUsing optical diodes in electronic devices are beneficial; by means of light, data processing speed can be enhanced, energy loss is reduced, and miniaturization is possible. However, because of light’s diffraction and interference, technology that can control light is necessary. Kim Min-kyung (ME, Ph.D. Integrated) and Professor Rho Jun-suk (ME, CE) have developed an optical diode that gives one-way light flow using symmetry-breaking metamaterials. Originally, the flow of an optical diode’s light is symmetrical, but using metamaterials, the research tea

From Sep. 22 to 23, the 16th POSTECH-KAIST Science War (PKSW)was held at the KAIST campus. Over 600 POSTECH supporters visited KAIST to join in and celebrate POSTECH’s victory.On the first day, Hacking, Football, A.I., and E-Sports took place. The first match, Hacking was carried out on the first day, from 9 A.M. Hacking games used to be started the day before PKSW and were conducted throughout the late evening, but due to player exhaustion, the game time was moved. By an overwhelming score of 1,321 to 717, POSTECH achieved victory. The next match was football. In the first half, POSTECH playe
