Abstract: A mobile inhaler is configured to provide an inhalable aerosol to a user. The mobile inhaler may include a vibrating mesh atomizer. The vibrating mesh atomizer may include a vibrating mesh membrane comprising a plurality of holes, a piezoelectric actuator coupled to the vibrating mesh membrane, wherein the processing equipment is configured to actuate the piezoelectric actuator, and a vibrating mesh membrane holder. The mobile inhaler includes processing equipment, which may include memory configured to store information about one or more users, including usage behaviour. A capsule is used to hold liquid for atomizing and may include a plunger to dispense liquid. The processing equipment may be configured to determine desired dosages, or other desired usage metrics, based on the stored information. In some embodiments, information from a plurality of mobile inhalers may be stored and analysed.
