Ultrasonic atomization is a very convenient method to produce sprays of very small
droplets. Resulting droplet size distributions are very narrow and the mean diameter is
essentially only controlled by the excitation frequency. Generation of droplets in the
micron range requires MHz waves, with voltages around 30 V, which translates into
power requirements on the order of 10 W. Tunable wave generators with these characteristics
are somewhat uncommon. To explore the capabilities of ultrasonic atomization
for inhalation therapies, an excitation source, described in this paper, has been designed.
The characteristics of the sprays obtained when driving with it a piezoceramic disk are
analyzed
