Abstract
[Problem] To provide a power feed system that supplies electric power via electromagnetic waves to an implant embedded in a deep part of a living body, using a sandwiching method in which a potential difference is generated using a pair of electrodes, by disposing an implant electronic device between a power transmission side electrode and a power reception side electrode.[Solution] It is provided with: a pair of electrodes (a first surface electrode 3 and a second surface electrode 4) stuck onto a surface of a living body 6; an implant electronic device 2 that includes a first body internal electrode 30 and a second body internal electrode 40 and in which the first body internal electrode 30 and the second body internal electrode 40 are fixed to respective positions having different potential differences in the living body 6; and a high frequency AC power source 5 that applies a high frequency alternating voltage to the first surface electrode 3 and the second surface electrode 4.
