ELECTRONIC VAPORISER SYSTEM
An electronic cigarette vaporiser system includes a piezo-electric pump ( 6 ) with multiple piezo-actuators, in which a microcontroller independently adjusts the phase or timing or power of each voltage pulse that triggers a piezo-actuator. The microcontroller continuously or regularly monitors the efficiency or performance of the entire pump ( 6 ) and adjusts the phase, timing, or power delivered to each piezo-actuator relationship until or so that the optimum pumping performance is achieved.
