Latest Patents
One of Didier Joyeux's latest patents is a method for propelling droplets of a conductive liquid. This innovative technique involves establishing a pulse of current of several hundreds of volts between two electrodes immersed in a resistive liquid. By concentrating the current at the end of one electrode, which is bonded onto an insulating support, a volume of liquid in contact with the end of this electrode is vaporized. This process causes an abrupt drop in current. Due to the high voltage of the pulse, a greater current re-establishes itself immediately across the volume of vaporized liquid, resulting in a sort of ionization of the vapor. This ionization leads to superheating and generates sufficient energy to expel a droplet of liquid through an opening provided in a membrane. To control the size of the droplets and limit the energy of the superheating phase, the current of the energizing pulse is carefully regulated. Another notable invention is the needle matrix printer, which showcases his expertise in developing advanced printing technologies.
