Abstract
This is a technology for non-contact power transmission to the laboratory animal biological information acquisition deviceembedded in the multiple laboratory animals in the breeding cage, and provides the power reception device, which can observe the behavior of laboratory animals from outside without covering the breeding cagewith the power transmission side, and which can continuously supply power regardless of the direction and position of the laboratory animals. The secondary coil partincludes a magnetic corehaving a circular cross-section perpendicular to the longitudinal direction, and a plurality of spiral coilsandformed by winding a conductor so that the outer shape is substantially rectangular. The spiral coilsandare arranged annularly in the circumferential direction of the magnetic coreso that the sides (and) and (and) are close to each other so as to cover the entire circumferential surface of the magnetic core(arranged to form a ring).
