The present disclosure relates to medicament injection devices. An injection device includes: a movable dosage programming component comprising a rotary encoder system having a predefined angular periodicity, a sensor arrangement including a first optical sensor configured to detect movement of the movable dosage programming component relative to the sensor arrangement during dosing of a medicament, wherein the first optical sensor is configured to operate in a strobe-sampling mode at a first frequency, a second optical sensor configured to detect movement of the rotary encoder system relative to the second optical sensor wherein the second optical sensor is configured to operate in a strobe-sampling mode at a second frequency lower than the first frequency, and a processor arrangement configured to, based on the detected movement, determine a medicament dosage administered by the injection device.

Medicament injection device

Implementations of the present disclosure are directed to an injection device including a medicament reservoir configured to store a medicament to be expelled by the injection device, and an acoustic source configured to generate an acoustic signal including information indicative of an amount of the medicament stored in the medicament reservoir. The acoustic signal is transmitted to an external device configured to process the acoustic signal and to extract injection device data.

Acoustic detection of a usage of an injection device

Implementations of the present disclosure are directed to an injection device () including a medicament reservoir () configured to store a medicament to be expelled by the injection device (), an acoustic source () configured to generate an acoustic signal including information indicative of an amount of the medicament stored in the medicament reservoir (), the acoustic signal being transmitted to an external device () configured to process the acoustic signal and to extract injection device data.

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.

Transmission of data associated with an injection device usage using passive RF modulation

Implementations of the present disclosure are directed to conserving energy of an injection device by using a sensor attached to the housing, the sensor configured to detect a signal associated with an amount of medicament within the injection device and to generate a sensor signal based on the signal, a control component coupled to the sensor, the control component configured to harvest energy to process the sensor signal and to generate injection device data, and an antenna coupled to the control component and configured to transmit a radio frequency signal based on the injection device data.
