7 . The method according to claim 1 , further comprising, prior to the first iteration of the characterization phase, a preliminary phase carried out when the implant is outside the body, said preliminary phase comprising at least one iteration of the following steps of:
measuring the implant outside of the body, by the at least one sensor known as the measurement sensor, by supplying at least one electrical signal, known as the reference signal; and
storing in a database, of the at least one reference signal in association with said at least one item of positioning data, referred to as an item of reference positioning data, of the implant.
8 . The method according to claim 1 , wherein the previously established model comprises:
a supervised neural network trained with a database and taking as input the at least one measured signal, said database linking an electrical signal with an item of positioning data, or
a pre-recorded table associating at least one electrical signal with at least one item of data relating to the positioning of said implant, or
a mathematical relationship between the at least one measured signal and the at least one item of positioning data.
