Abstract
Implementations of the present disclosure are directed to an injection device including: a reservoir including a wall defining a proximal end, a distal end and a tubular side, a plunger rod configured to be movable within the reservoir in a direction from the distal end to the proximal end, a radio frequency (RF) antenna attached to the tubular side and configured to receive an interrogation signal from an external device, and a resonating assembly configured to receive the interrogation signal from the RF antenna and to generate a modulated RF signal having a frequency associated with a position of the plunger rod.

An injection device comprising:
- a reservoir comprising a wall defining a proximal end, a distal end and a tubular side;
- a plunger rod configured to be movable within the reservoir in a direction from the distal end to the proximal end;
- a radio frequency (RF) antenna attached to the tubular side and configured to receive an interrogation signal from an external device;
- and
- a resonating assembly configured to receive the interrogation signal from the RF antenna and to generate a modulated RF signal in response to the interrogation signal, the RF signal having a frequency associated with a position of the plunger rod,
- wherein the interrogation signal comprises a plurality of interrogation signals received at regular time intervals, and
- wherein, in response to receiving the plurality of interrogation signals, the resonating assembly generates a plurality of RF signals, such that a frequency shift between two of the plurality of RF signals is associated with an amount of medicament within the reservoir.
