1. An indication system for use in a drug delivery device, the indication system comprising:
a housing;
a moveable component configured to move with respect to the housing during operation of the drug delivery device;
an electric circuit having an electrical property, the electric circuit comprising:
an electrical component operatively coupled to the moveable component and configured to modify the electrical property based on a position of the moveable component, such that the electrical property of the electric circuit is an indication of the position of the moveable component, and
an electric contact on an exterior of the housing; and
an electronic-ink label configured to be disposed on the exterior of the housing, the electronic-ink label comprising:
printed electronics arranged to be in electrical communication with the electric circuit via the electric contact and configured to display a visual indication related to the position of the moveable component in response to the electrical property of the electric circuit,
wherein the electrical component comprises:
a first component comprising:
a track spanning at least a portion of a length of the first component, and
first and second conductors, each extending continuously along an entire length of the track, the entire length spanning between a distal most end and a proximal most end of the track; and
a second component that is conductive and moveable with respect to the first component along the track, the second component contacting the first and second conductors, wherein the electrical property is proportional to a position of the second component along the length of the first component,
wherein the moveable component of the drug delivery device comprises the first component or the second component, and
wherein the position of the second component with respect to the first component is changed during a dose setting operation or a dose dispensing operation of the drug delivery device.
