According to the company, Apple’s method utilizes a solid-state air mover using “corona discharge—an electrical discharge near a charged conductor caused by the ionization of the surrounding air.” This is made of one corona electrode, one collector electrode, and a high voltage power supply. An electric field is created when voltage is applied to electrodes; the electric field causes surrounding particles to become ionized (charged). The electric field “spreads” a charge toward the collector electrode, and the charge continues to spread and create air movement en masse.
