A wireless power transfer system for such applications of wearable or medical implantable devices has been developed. Fast tracking loop for load variation and electro-magnetic interference (EMI) suppression techniques are implemented in the developed wireless power transfer system.

Novel optoelectronic devices are realized by using nanocarbon materials such as carbon nanotubes and graphene.

Using each electron embedded near a diamond surface as a pixel for quantum sensing, magnetic field imaging of the substance placed on top of the diamond surface is realized.

This is an ultra low power reconfigurable accelerator for battery-driven devices. This chip can execute some image processing applications with less than 1-mW power consumption. Today, we will show you a demo of executing an application by using a lemon battery.

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.

We propose an on-chip power supply for the millimeter scale system operating autonomously. The power supply system using a standard CMOS process is composed of solar cell which outputs about 0.5V and DC-DC boost converter on a same die. The output voltage of the power supply system is more than 1V which is able to operate general analog circuits.

Modular smart phones have been attracting attention because users can freely customize and update their phones by selecting modules. The non-contact interface technique is demonstrated for high-speed and high-quality communication between modules.
