Determining Resonance Frequency and Ultrasonic Nebulizer Boards
When exposed to an AC electric field, a piezoelectric ceramic element changes dimensions cyclically, at the cycling frequency of the field. The frequency at which the ceramic element vibrates most readily, and most efficiently converts the electrical energy input into mechanical energy, is the resonance frequency.
The pattern of an

Piezo Breeze Sensors and Value Added Services APC Provides
Piezo Breeze Sensors are a different approach to measuring air flow using piezoelectric ceramics.
A piezo breeze sensor discloses increases in the velocity of the air or other gas to which it is exposed. The sensor contains two piezoelectric elements in a series-opposed circuit.
One element is exposed to the gas whose
