摘要：
Various arrangements for determining an atomization element of a nebulizer is dry are presented. The vibratable element of the nebulizer may be energized with an electrical signal that sweeps from a first frequency to a second frequency. While energizing the vibratable element of the nebulizer with the electrical signal that sweeps from the first frequency to the second frequency, a sequence of impedance values of the vibratable element of the nebulizer may be measured. The sequence of impedance values of the vibratable element of the nebulizer may be analyzed to determine if the atomization element of the nebulizer is wet or dry.
