<p>An inhaler (220) that utilizes vibration to facilitate suspension of powder into an air stream is provided. One embodiment of the inhaler includes a piezoelectric vibrator (254) for vibrating the powder. A controller is provided for controlling supply of actuating electricity to the vibrator so as to cause the powder to vibrate in such a way as to deaggregate the powder and separate the powder by size. The powder particles of interest are then suspended in the air stream by electrostatic means (232).</p> |
