Small-size and low-power sensor systems where nano-materials are utilized are introduced. The sensors detect gaseous molecules as well as volatile organic compounds (VOC). Because of low-energy properties, it can be integrated in mobile devices such as smart phone and will be utilized to monitor health conditions of users.

Research and development of Graphene material growth, device & process, and simulation technologies for LSI interconnect applications.

Optical microcavity can detect small environmental change, which allows us to use this device as gas and pH optical sensor. It also enables the conversion of a continuous wave light into ultrahigh repetition rate pulse trains. Such studies remained basic researches, but we are now trying to move into an application stage by integrating the device with a fiber and enable to carry it out from the laboratory.

In the development of practical devices for human-machine system, adaptive system design is required for the device users and the environment. Taking these requirements into accounts, our research group focuses on intelligent machine system such as walking assist device and prevention system of falling down by the monitoring of human motion and the development of the advanced algorithm based on force control.

Wide-field imaging of weak magnetic field is demonstrated by using electrons in diamond as a magnetic field sensors. High sensitivity and high spatial resolution for measuring magnetic field can be achieved by utilizing quantum properties of electrons in diamond.

We show some cutting-edge embedded technologies such as Responsive Multithreaded Processor (RMTP) for parallel distributed real-time system applied like humanoid robot control, RMTP SoC, RMTP SiP and Responsive Link, which is a real-time communication standard.

Our research demonstrates high-speed non-contact interface using transmission line coupler (TLC). Proximity communication with a wireless power supply provides immunity to mechanical damages caused by vibration/friction and isolation from water/chemicals while reducing fabrication costs. These features are suitable for medical and automotive applications where high reliability is demanded.

We introduce an advanced prosthetic hand “general purpose artificial hand.” This artificial hand substitutes physical sensation of healthy body part for that of lost body part. By the haptic transplant technology, human-like strong, dexterous, and adaptive motions are realized.
