Research Highlights

Soft robotic gripper based on dielectric elastomer actuators

Soft robots that are composed of compliant materials offer important advantages over conventional rigid robots, such as simplified body structure and control, as well as high robustness and versatility.

Digital Public Media: Mid-air Display Technology

Recently, virtual reality technology plays an important role as an interface between current cyber physical systems and wearable displays, and HMD is HMD is a hot topic. The problem with wearables is that the same information cannot be shared by many users even though they are in the same space. It needs other information presentation and sharing methods that people share together.

Molecular materials with ultralong-lived room-temperature triplet excitons

The lifetime of triplet state of molecular materials is generally shorter than 1 ms at room-temperature (RT) because nonradiative deactivation of the triplet state is usually rapid at RT. However, if the fast nonradiative deactivation from the triplet state is largely suppressed, triplet excitons with a very long lifetime at RT can form. Molecular materials with the long exciton lifetimes could potentially lead to the realization of new applications that are unfeasible using conventional molecular materials with short exciton lifetimes.
