Abstract

A power supply apparatus supplies power to a body-insertable apparatus from outside a subject. The body-insertable apparatus is introduced into the subject and obtains intra-subject information. The power supply apparatus includes a first electric cable which is wound around a circumferential surface of a garment and forms a coil, the garment covering the subject, the coil having a non-directionality at a time of power supply; and a power supply unit which supplies power to the body-insertable apparatus in a contactless manner through the coil.

Claims

1. A power supply apparatus which supplies power to a body-insertable apparatus from outside a subject, the body-insertable apparatus being introduced into the subject and obtaining intra-subject information, the power supply apparatus comprising:

a garment that covers the subject;

a power-supply coil having loops with non-concentric central axes and arranged in and continuously wound around the garment to intersect with itself at a front side and a back side of the garment on an inner circumferential surface of the garment, the power-supply coil being placed at a predetermined horizontal pitch at both sides of the garment; and

a power supply unit that supplies power to the body-insertable apparatus in a contactless manner through the power-supply coil.
