• input element such as buttons, switches, touch panels or similar interface elements that allow a user of the aerosol generation device to provide operation input for the device.
• the user may, for example, turn the aerosol generation device on or off, adjust one or more operation parameters of the device such as a heating temperature or duration, or may input a request for the aerosol generation device to output, for example, information pertaining to an operational state of the aerosol generation device.
• Some configurations provide one or more input elements that are accessible at the exterior surface of an outer device housing of the aerosol generation device. While the input elements are easily accessible, such configurations are prone to unintentional actuation of the input elements. Furthermore, they are subject to mechanical wear and tear and are not protected from ingress of liquids and small particles and particulates.
• Some configurations utilize a cover panel that covers input elements provided on a main body of the aerosol generation device. The cover panel can typically be detached or otherwise moved relative to the main body to expose the input elements to a user of the aerosol generation device.

Therefore, using a panel for the cover element decreases manufacturing costs and complexity.
• the one or more flexible regions of the panel have an average material thickness smaller than an average material thickness of the non-flexible regions.

• the aerosol generation device comprises circuitry for controlling the operation of the aerosol generation device based on information from the cover detection means, the information comprising information about a first state in which it is detected that the cover element is attached to the main housing and about a second state in which it is detected that the cover element is not attached to the main housing.
• Proper positioning and attachment of the cover element are important for ensuring that a user may properly and safely operate the aerosol generation device, i.e. that a user input by pressing onto a flexible region of the cover element actuates the operation interface portion as intended, and is further important for ensuring proper protection of the operation interface portion from potentially harmful external influences.
