A sensor assembly for a vaporizer device for delivery of an aerosol for inhalation by a user, comprising: at least one substrate; a flexible sensor having at least one end coupled to the at least one substrate, the flexible sensor being configured to reversibly deflect from an initial state to a first state in response to a first user-activated force representing air being drawn through an airflow path of a vaporizer device, and the flexible sensor being configured to reversibly deflect from the initial state to a second state in response to a second user-activated force representing an acceleration of the vaporizer device; and characterized by a controller configured to: receive a deflection signal in response to deflection of the flexible sensor, maintain a first frequency threshold and a second frequency threshold, compare the deflection signal to the first frequency threshold and the second frequency threshold, output a first signal when a frequency value associated with the deflection signal is less than the first frequency threshold, the first signal being associated with air being drawn through the airflow path; and output a second signal when the frequency value associated with the deflection signal is greater than the second frequency threshold, the second signal being associated with acceleration of the vaporizer device. at least one substrate; a flexible sensor having at least one end coupled to the at least one substrate, the flexible sensor being configured to reversibly deflect from an initial state to a first state in response to a first user-activated force representing air being drawn through an airflow path of a vaporizer device, and the flexible sensor being configured to reversibly deflect from the initial state to a second state in response to a second user-activated force representing an acceleration of the vaporizer device; and characterized by a controller configured to: receive a deflection signal in response to deflection of the flexible sensor, maintain a first frequency threshold and a second frequency threshold, compare the deflection signal to the first frequency threshold and the second frequency threshold, output a first signal when a frequency value associated with the deflection signal is less than the first frequency threshold, the first signal being associated with air being drawn through the airflow path; and output a second signal when the frequency value associated with the deflection signal is greater than the second frequency threshold, the second signal being associated with acceleration of the vaporizer device. receive a deflection signal in response to deflection of the flexible sensor, maintain a first frequency threshold and a second frequency threshold, compare the deflection signal to the first frequency threshold and the second frequency threshold, output a first signal when a frequency value associated with the deflection signal is less than the first frequency threshold, the first signal being associated with air being drawn through the airflow path; and output a second signal when the frequency value associated with the deflection signal is greater than the second frequency threshold, the second signal being associated with acceleration of the vaporizer device.
