Abstract | The present disclosure relates to a medication delivery device comprising: a device body having a longitudinal axis; a dose setting member coupled to the device body and rotatable relative to the device body during a dose dispensing operation; an actuator coupled to the 5 device body and movable relative to the device body during the dose dispensing operation; and a dose detection system configured to detect rotation of the dose setting member during the dose dispensing operation, the dose detection system comprising: at least one deformable member; at least one piezoelectric sensor coupled to the at least one deformable member; and a plurality of force applicators arranged in a helical pattern on an outer surface of the dose 0 setting member, wherein each force applicator is configured to apply a mechanical force to the at least one deformable member and deform the piezoelectric sensor during the dose dispensing operation.. |
