There is a battery problem that is a major barrier to the spread of electric vehicles. We will propose "Via-Wheel Power Transfer (V-WPT)" as a breakthrough to solve this problem and aim to establish technology for power supply while driving.
Current drones have the drawback of requiring manpower to charge or replace the battery, which is an obstacle to expanding the flight distance. Therefore, we received a commission from the Cabinet Office Strategic Innovation Creation Program and started research on "wireless power supply drones".
We aim to realize a high frequency power supply that can be used in a wide range of fields and satisfies high levels of high frequency, high efficiency, large power output, load fluctuation resistance, etc.
Oscillating circuits are the source of all radio waves, and there are countless possible topologies. We create original circuit configurations by making full use of active devices and lumped/distributed constant elements.
Research on secret keys using the complexity of the radio wave environment. We also devised a method for estimating the direction of arrival of radio waves, and researched ESPAR antennas.

"Radio waves" are eternal media shared by humankind. Radio waves are expected to be used in broadcasting, communications, sensing, and as a means of transmitting energy. In our laboratory, we are pioneering variable directional antennas and their radio wave application technology. Furthermore, by utilizing the ICT technology we have cultivated in the field of green innovation, we will utilize direct current energy generated by solar and wind power. Intelligent power technology that efficiently converts to AC power for home use and the electrification of major highways We are also researching new electric vehicles that can continue to run. AttentionA new interpretation of the kQ theory: Expanded to be applicable to electric field coupling
