Abstract (in Japanese) (See Japanese page) 
(in English) With the advancement of autonomous driving and electrification of vehicles, an increase in the number of onboard sensors is expected. Supplying power to each sensor via wired connections can lead to increased costs and weight due to power and communication cables. In this study, we examined wireless power transmission using a spatial transmission method to supply power to each sensor. We confirmed that a temperature sensor embedded in the headrest could operate at 30-second intervals using wireless power transmission at a transmission frequency of 920MHz and transmission power of 1W. Additionally, we simulated the distribution of electric field intensity inside the vehicle cabin and confirmed that in most areas of the cabin, the electric field intensity necessary for the sensor to operate could be achieved.
