Investigation of a Transmitting/Receiving Coil Configuration Suitable for Constructing a Contactless Power Supply to a Biometric Information Acquisition Device

This study aims to construct an implantable biometric device for real-time monitoring of biological information of laboratory animals. The primary purpose is to construct a system that can constantly transmit power to the device without contact. The most useful method is a contactless power supply that applies electromagnetic induction between the coils. Therefore, we investigate the optimal magnetic field configuration to supply power to the biometric device, as well as the shapes of the transmitting and receiving coils, and conduct a demonstration experiment.
