Smart sensors are employed to determine one or more of
drug identification,
dose, flow rate, concentration, agglomeration, and degradation and / or other characteristics of
drug administration that can be detected via sensing technology. A smart sensor(s) can be coupled to or retrofitted onto injection pen injectors and / or
drug delivery cartridges and / or infusion sets or cannulae, enabling infusion sets,
pen injector systems or
drug delivery cartridges to improve tracking of drug self-administration and stop medication errors that occur primarily through self or automated injection (e.g., due to incorrect or incomplete dosing, excessive
dose or rate, incorrect drug, or
drug degradation).
