A method and device for driving a piezoelectric device |
| abstract |
There is presented a method for driving a piezoelectric device and an atomizer for atomizing a fluid, and an atomization method for a fluid using a piezoelectric device; the atomizer employs a piezoelectric device and circuitry that uses a switching voltage across the piezoelectric device at an operating frequency; sensing a sensed voltage corresponding to a phase of the piezoelectric device; and responsive to whether the sensed voltage is in phase or out of phase relative to the switching voltage, changing the operating frequency provided to the piezoelectric device, and the changing is one of: increasing the operating frequency by a first value, or decreasing the operating frequency by a second value. |
