A dosage sensing module for or in a pen drug delivery device and comprising a power source unit, a processor unit and a dosage sensor unit with a first sensor part adapted to be fixed to a part not rotating during dose expelling and comprising a flexible printed circuit board sheet on which a pattern of individual electrical conductive sensor areas are arranged. The sensor unit further comprises asecond sensor part adapted to be fixed to the piston rod to follow the rotation thereof during dose expelling. The second sensor part comprises individual structures that together with the conductivesensor areas are adapted to, upon relative rotational movement between the first and second sensor part, provide electrical signals to a processor unit indicative of the relative rotational positionbetween the first and second sensor part. 一种用于或在笔式药物递送装置中的剂量感测模块，所述剂量感测模块包括电源单元、处理器单元以及剂量传感器单元，所述剂量传感器单元具有适于固定到在剂量排出期间不旋转的部分的第一传感器部分并且包括其上布置有单独的导电传感器区域的图案的柔性印刷电路板片。传感器单元还包括适于固定到活塞杆以在剂量排出期间跟随其旋转的第二传感器部分。第二传感器部分包括单独的结构，所述结构与导电传感器
