Luminescent material for a highly-sensitive in vivo imaging that can visualize to a depth of 5-6cm from the epidermis

In recent years, "Bioimaging", which can observe the development process of disease in real-time by using fluorescent agents (bioprobes) to illuminate intracellular proteins, has been attracting attention. In this study, we developed a luminescent substrate that gives an emission peak within the biological window (650 nm ～900 nm) at which “imaging to a depth of 5-6cm from the epidermis is possible”, using the bioluminescent system of a firefly. The substrate is neutral and highly soluble, and can also be used to analyze the areas with high blood flow such as the brain and lungs. It can be expected to be used not only in oncology and regenerative medicine, but also in bioluminescence imaging in organisms such as miniature pigs and marmosets. Any company or laboratory that is willing to utilize this technology is welcome.

Safer and low-cost breast cancer examination technology by utilizing microwave radar and tomography

X-ray mammography is used for breast cancer examination, but females’ acceptance rate of examination is only about 15% because the X-ray based examination causes radiation exposure and strong pain with high pressure to the breast.
In order to develop a more comfortable and frequent breast cancer examination technology, we focused on microwave mammography apparatus utilizing a physical basis for the high contrast of complex permittivity between cancer cells and normal cells. Finally, we developed a highly accurate cancer detection method by combining unique radar technology called as PRM (Range Points Migration) method and the tomography technology, also introducing machine learning system upon artificial intelligence. This new examination technology can detect cancer cells less than 1 cm on the early stage.

Microwave and millimeter wave radar imaging technology, which can work even under bad weather and bad visibility, using the Doppler velocity and multiple scattering waves

Under the severe environments such as dust, darkness, high concentration of gas, and strong backlight, those deteriorate the performance of ordinary cameras or sensors for detecting victims, obstacles and so on.
This study is to detect the target objects and obstacles exactly in real time even under the bad environments by combining the unique technology called as Range Points Migration (RPM) method and the estimation technology of Doppler velocity on the human body into UWB radar. Finally, we developed a new technology. Since this technology has deep penetration performance, it can be utilized for rescue / resource exploration robots, on-vehicle sensor, etc.

Nondestructive examination technology for inside of concrete by combining radar and tomography – detecting cavities and corrosions

The deterioration of social infrastructures such as roads, bridges, tunnels, etc. is an urgent critical issue closely related to The National Resilience Plan and the nondestructive examination technology is highlighted to examine the status of deterioration. In our laboratory, we have been studying a new nondestructive examination technology by combining UWB (Ultra-Wideband) radar and RPM(Range Points Migration) which is a unique technology as well as tomography technology in order to examine inside status (cavities, water distributions) of especially concrete construction materials exactly and efficiently for secured maintenance. Particularly, introducing the tomography technology can obtain information of permittivity and dramatically improve the accuracy of discrimination for cavities and corrosions.

Small-sized shape memory alloy (SMA) artificial muscle actuator with high responsivity and flexibility that can be attached directly to human body

In recent years, artificial muscles have attracted attention for the purpose of power assistance by mounting to human body, and the development of artificial muscles using electric motors and air pressure is underway. However, electric motors have issues on low power generation and flexibility per weight, while artificial muscles using pneumatic rubber have issues on responsivity, quietness, and mobility (portability).
The system shown here was realized by a joint research between Kaneko Code Co., Ltd. and Nakamura Group in Department of Science and Engineering, Chuo University. This epoch-making system solved the issue of low responsivity, the top issue of SMA actuator. The response speed of this system is 5 times faster than that of conventional SMA actuator. Also, this system can be reduced in size and weight and can be attached directly to the human body thanks to its high flexibility. Therefore, this system is expected to have multiple applications including medical use. We welcome companies that are motivated to develop applied products and businesses using this technology.

Application of 254 nm ultraviolet emission electrodeless lamp system with low power consumption and long life time to sterilization systems

The developed ultraviolet emission electrodeless lamps shows strong emission at 254 nm and can be used for sterilization systems. Other applications can be considered using such properties as high-efficiency, small-size, and long-life. Though the low power microwave is used to ignite the lamps, there is almost no leakage of microwaves. Therefore there is no electromagnetic effect on the peripheral device or systems. In combination with our compact 2.45 GHz microwave oscillator, it is possible to construct sterilization systems with low power consumption and long life, which are small and relatively inexpensive. We welcome to companies that wish to introduce and apply this product.

Impedance matching tuners (automatic and manual) for microwave circuit

Tuners for impedance matching can decrease the reflected microwave power from external load in microwave circuits so that it is important to effectively use the microwave input power. In particular, for loads such as microwave plasma where the impedance fluctuates easily, it is necessary to continuously perform impedance matching. In this lab, compact automatic matching tuners (Auto　Tuner) have been developed to realize impedance matching in a short time. Compact and lightweight manual matching tuners for 400MHz, 915MHz, 2.45GHz and 5.8GHz have been commercialized. All of these products have been widely used as convenient tools. These products are available not only for plasma generation circuits, but also for microwave applications such as microwave heating reactors.
