An inhalation device for delivering medication to a user may include a mouthpiece, a dosing chamber, and a flow channel connecting the mouthpiece to the dosing chamber. The dosing chamber may be configured to deliver the medication to the user via the mouthpiece. The inhalation device may include an electronically driven vibratory element, a sensor system configured to generate a pressure signal indicative of air flow through the flow channel, and a controller. The controller may be configured to receive the pressure signal from the sensor system (e.g., a micro-electrical mechanical (MEMS) pressure sensor). The controller may be configured to perform an inhalation detection procedure to determine a plurality of successful inhalations. For example, the controller may be configured to generate a trigger signal to control timing of operation of the electronically driven vibratory element to release medication into the dosing chamber based on the plurality of successful inhalations. |
