Abstract: A pill removal detection device for a blister package including a metallic element. Further, the pill removal detection device includes a detection means for detecting removal of a pill from the blister package. Yet further, the pill removal detection device includes an energy source, a sensor for detecting a change in capacitance of the metallic element of the blister package, means for communicating the detected change in capacitance to the detection means for waking up the detection means, and an attachment means for attaching the pill removal detection device to the blister package, the attachment means including an electrically conductive element connected to the sensor.
