When using a conventional inhaler, the user must press the release valve manually to breathe the mist into the lungs during breathing. They may not receive enough inhaled drugs.
The digital inhaler senses when the user will inhale, and then automatically releases the fog through an electronic injector. This is said to avoid speculation, to ensure that the drug is fully released, and that no propellant is needed.
In addition, the device can be synchronized with the user's smartphone to keep their treatment records, so that they do not miss any dose.
It's not clear when a digital inhaler can be approved for widespread use, and it is still considered a research device for a while.
