Abstract: An aerosol-generating device is provided, including: a heater, a component of the heater including a coating, the coating being formed from a glass composition including: between about 30 percent by weight and about 70 percent by weight silicon oxide, between about 0.1 percent by weight and about 10 percent by weight aluminium oxide, between about 2 percent by weight and about 30 percent by weight boron oxide, between about 2 percent by weight and about 40 percent by weight lithium oxide, between about 0.1 percent by weight and about 5 percent by weight magnesium oxide, and one or more of calcium oxide, gallium oxide, potassium oxide, samarium oxide, strontium oxide, and titanium oxide. An aerosol-generating system including an aerosol-generating article and the aerosol-generating device is also provided.

Abstract: An aerosol-generating system is provided, including: an aerosol-generator housing; and a piezoelectric transducer having an elliptical shape and including a first region and a second region, the second region being electrically isolated from the first region, and the piezoelectric transducer being secured to the aerosol-generator housing at a single attachment point positioned only within the first region.
