538 Development of MEMS Tactile Display with Displacement Amplification Mechanism
Details
Virtual reality is becoming more and more important as an intuitive information transmission technology. Particularly tactile display is necessary for more advanced virtual reality. Previous tactile displays are divided into two types. One can display feelings of displacement like "rough" and "rugged" by generating displacement, the other can create illusions of texture like "smooth" and "textured" by generating vibration. However, it is problematic to realize two types at once because of the problems of drive mechanism and so on. In this research, we develop displacement amplification mechanism, which can be easily downsized and arrayed, by using MEMS technology. Displacement amplification mechanism is made up of large displacement PDMS and two chambers. Each chamber has different cross-section which can amplify displacement PDMS. Then, displacement amplification mechanism is driven by piezo actuator, and we aim to generate more real tactile feelings combining enough displacement and vibration.
