摘要：
An electrostatic spraying device (1) and method for dispensing a controlled volume of liquid in pulses using an emitter (2) having a spray area (29) from which the liquid can be sprayed, a means for injecting charges into the liquid, whereby, in use, the liquid (3) is delivered to the spray area by electrostatic forces and electrostatic spraying occurs in one or more pulses whilst the charges are injected. The charges may be injected by a time-varying or constant non-zero electric field so that electrospray occurs above a threshold value.
