Delivery system for generating liquid active materials using an electromechanical transdcuer

A method of distributing a liquid active material to an atmosphere, said method comprising the steps of:

• (a) providing a quantity of said liquid active material;
• (b) providing an electromechanical transducer in communication with said liquid active material;
• (c) activating said electromechanical transducer to distribute said liquid to said atmosphere;
• and
• (d) carrying out said activation for a first period of time of at least about 20 milliseconds.

A method of distributing a liquid to an atmosphere, said method comprising the steps of:

• (a) providing a quantity of said liquid;
• (b) providing an electromechanical transducer in communication with said liquid
• (c) activating said electromechanical transducer for a first period;
• (d) deactivating the transducer for a second period, said first period and said second period forming an operating cycle;
• and
• (e) repeating said operating cycle at least once;
• wherein said electromechanical transducer defines a plurality of perforations, said perforations having a diameter of about 5 microns to about 7 microns and wherein said first period is at least about 20 milliseconds.
