Abstract: A portable inhalator device includes a housing with a mouthpiece for a user; a gas conduit coupled to the mouthpiece and configured to guide inhaling and exhaling gas flow within the device; a pressure sensor configured to monitor the gas flow in the gas conduit and to provide pressure differential signal for indicating direction of the gas flow through the gas conduit; a detection sensor configured to monitor the gas flow in the gas conduit and to provide characteristics signal for indicating composition of the gas flow through the gas conduit; and a dispenser configured to dispense a drug to the gas conduit.

Abstract: A piezoelectric device comprises at least one element comprising at least one sheet of piezoelectric material. The element is mounted on a circuit board comprising at least one conductive layer having at least one opening. The element is located on the opening and supported by edges of the opening in such a manner that the opening extends laterally beyond the area of the sheet of piezoelectric material. The element is sandwiched between an overlay and the circuit board in such a manner that vibrations of the sheet of piezoelectric material are sufficient to cause vibration of the overlay.
