The present invention provides improved devices, components, and conduit assemblies for delivery of a breathable/inhalable fluid stream containing a solvation-enhancing atomized liquid, the fluid stream carrying a functional liquid component. In one aspect, devices of the invention incorporate an exchangeable fluid-permeable body, such as a cartridge comprising a fluid-permeable packing material, containing the functional liquid. In another aspect, devices of the invention incorporate an electronic control system configured to detect and store physical states, settings, modes/configurations, and/or usage of the device over time. Optionally, the detected states may be exported to a separate electronic device via a Wi-Fi or other suitable remote connection. In other embodiments, the electronic control system provides passcode authorization for actuating an atomizing element and/or toggling the device between locked and unlocked states.
