A usage recording smart label and inhaler, and methods for detecting, verifying and recording actuation events of the inhaler, are disclosed. The usage recording smart label comprises a capacitive touch sensing plate to detect the presence of an activating body organ such as a hand or finger. The smart label, which may be in the form of a sticker or sticker-like, is attached to a grasping or actuation surface of the inhaler. The smart label may comprise text printed thereon, used as a replacement for an existing printed label. A usage recording method comprises (a) the usage recording smart label detecting an event of proximity of a finger for a given minimal time duration; (b) recording a timestamp of the event in memory of the smart label; (c) communicating stored timestamp data from the memory to an external device; the external device can be configured to display the actuation history. |
