Proposal of a transmitting and receiving coil configuration focusing on contactless power supply to biometric information acquisition devices for small experimental animals

In developing drugs and medical technologies, it is essential to research their actions and side effects using animal experimentation. In order to study the effects of drugs and technologies on experimental animals, it is necessary to collect biometric information such as animal activity, body temperature, heart rate, and blood pressure. To date, battery-powered implanted devices have been used to collect biometric information. However, these have the disadvantage of not being able to collect real-time information due to battery capacity. To solve this problem, we propose that biometric acquisition devices be driven by a contactless power supply. The shape of a transmitting and receiving coil is studied to enable power to be supplied to an implantable device regardless of the position and posture of the experimental animal. This allows us to construct a system with non-directional characteristics.
