Development of a flexible tactile display based on liquid-to-gas phase change microactuator array

Professor Jongbaeg Kim’s research group in the Department of Mechanical Engineering developed a flexible tactile display that can be attached to the skin to transmit sophisticated tactile information. For sophisticated tactile transmission, this research team used a phase change actuator that can produce large output during liquid to gas phase change, and developed a device with higher spatial resolution than previous studies to enable more realistic tactile transmission to users. The study was presented at the 2023 36th IEEE MEMS Conference, the most prestigious academic conference in the MEMS field. On a basis of the excellence of the research, the presentation was selected as the Outstanding Student Poster Presentation Award Finalist, which is awarded only to 10 poster presenters among a total of 635 papers.
