Method for producing insulated electrodes for applying electric field into conductive materials

The present invention relates to a method for producing an insulated electrode comprising a conductive material coated with an electrically insulating material. Said method comprises at least the following step of: - forming a mould in an electrically insulating material, said mould comprising at least one channel, said mould being adapted to confine a conductive material, - introducing the conductive material in a liquid state into the channel of said mould, said conductive material having a melting point that is lower than the melting point of the electrically insulating material.
