Research Activities

Electrostatic Actuation:
We have been working on a wide range of electrostatic actuation technologies in the macroscopic scale. Electrostatic acutation can realize unique systems having special features, such as thin, light-weight, and transparent. Fully utilizing such unique characteristics, we have been developing innovative mechatronic systems.
- Electrostatic active display, to realize physical actuations on a visual display.
- Electrostatic visuo-haptic system, on which users can feel force feedback from visual information.
- Electrostatic paper handling.
- Electrostatic wall climbing robot.
- High-power electrostatic artificial muscle for robotic applications.

Haptic/tactile technologies:
We have been studying novel haptic/tactile technologies to enhance reality in tele-operations and virtual reality.
- Tactile displays to reproduce surface texture feelings, which include surface roughness, themal feeling, and softness feeling.
- Pseudo-haptic technologies using tactile stimulations.
- Human operation support using haptics.
