Abstract
An inhaler that uses capillary effects to output droplets of pharmaceutical product is described. The inhaler includes transducers and lenses to generate focused acoustic waves. The frequency and pulse width output of the transducers are set to cause capillary action in a reservoir of pharmaceutical product. The capillary action results in the ejection of small droplets of pharmaceutical product at low frequencies.
