The invention relates to a method for preparing a part (10) so as to enable said part to be controlled by guided waves generated by the magnetostrictive effect. After being prepared, the part (10) has two parallel basic strips (41a, 41b) close together on a first portion (11) of the surface thereof, at least one of the strips (41a) being non-continuous, wherein each of the strips (41a, 41b) has magnetostrictive properties.
