Abstract

An fluid sensor to activate and control various components of an inhalation device. The fluid sensor includes an acoustic element, such as a microphone, positioned within said inhalation device to detect fluid within the device and output signals representative of the frequency and/or amplitude of the fluid. These signals control and activate an electrostatic plate and/or a high frequency vibrator.
