Power supply apparatus

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.

1 . A power-supply coil for a power supply apparatus that 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, wherein
 the power-supply coil has adhesiveness.   
     
     
         2 . The power-supply coil for a power supply apparatus according to  claim 1 , comprising:
 a sheet member.   
     
     
         3 . A method of supplying 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 method comprising:
 attaching a power-supply coil to at least one of the subject and a garment the subject wears; and   supplying power to the power-supply coil.
