Early intratracheal instillation of budesonide using surfactant as a vehicle to prevent chronic lung disease in preterm infants: A pilot study

In an exemplary embodiment of the disclosed transformer, the transformer comprises a dielectric area. For example, the dielectric area can consist of three different dielectric layers. Also, by way of example, the dielectric area can comprise silicon dioxide or a low-k dielectric. According to the exemplary embodiment, the dielectric area is interspersed with a permeability conversion material. The permeability conversion material has a permeability higher than the permeability of the dielectric area. For example, the permeability conversion material can be nickel, iron, nickel-iron alloy, or magnetic oxide. The exemplary embodiment further comprises a first conductor and also a second conductor patterned into the dielectric area. The first and/or the second conductor can comprise copper, aluminum, or a copper-aluminum alloy. Each of the first and second conductors are made up of a number of turns which result in, respectively, the primary and secondary windings of the exemplary disclosed transformer.
