Abstract

Various methods, devices, and systems are described for aerosolizing a liquid. Embodiments may include sealing the liquid within a reservoir. An output waveform signal may be generated. A nebulizer element may be vibrated to aerosolize the liquid. A negative pressure may be produced within the reservoir as the liquid is aerosolized. The output waveform signal may cause the nebulizer element to vibrate. Embodiments may involve determining a phase shift between a current of the output waveform signal and a voltage of the output waveform signal. Also, embodiments may involve adjusting a frequency of the output waveform signal at least partially based on the phase shift. Further, embodiments may involve adjusting the voltage of the output waveform signal at least partially based on the frequency of the output waveform signal.
