Abstract
Atomizer cores, atomizer core substrates and methods of manufacturing atomizer core substrates are provided as well as aerosol generating devices incorporating same. In one example, the atomizer core comprises a core body having a first surface and a second surface. The core body includes a substrate and a heater with a plurality of channels extending between the first surface and the second surface for transferring an aerosol precursor from the first surface through the substrate and the heater to the second surface, the heater being adapted to heat the aerosol precursor to form an aerosol at the second surface. In other embodiments an insulator is disposed between the substrate and heater and adapted to insulate the substrate at least partially from heat generated by the heater.
