The invention consists of an adhesive support of destructible material on which a "printed circuit" is traced, by means of conductive ink, called the detector PCB. The invention envisages applying this adhesive support of destructible material over the "closing sheet" of the blister. This printed circuit, called the detector PCB, is traced so as to cross the surface corresponding to each bubble of the blister containing the unit. If you want to take the unit from the blister, by exerting pressure on the blister bubble, the closure sheet is broken； in this way also the adhesive support is broken and with it the trace of the detector PCB. The circuit is thus "opened". Using the detector PCB terminals connected to a service device, pick-up is detected. This service device can be designed in such a way as to collect the data relating to the collection of each unit (day, time, sequence) and keep a diary which, once connected to an interface such as a smartphone, or other device, can be made available. both of the patient and of other users authorized by the patient. This device, through a sensory signal, noise or light, will remind the patient of the time of administration of the drug. These services will facilitate the adherence to the prescribed therapy.L’invenzione consiste in un supporto adesivo di materiale distruttibile su cui viene tracciato un «circuito stampato», mediante inchiostro conduttore, detto PCB rivelatore. L’invenzione prevede di applicare tale supporto adesivo di materiale distruttibile sopra il «foglio di chiusura» del blister. Tale circuito stampato, detto PCB rivelatore, è tracciato in modo da attraversare la superficie corrispondente a ciascuna bolla del blister contenente l’unità. Volendo prelevare l’unità dal blister, esercitando pressione sulla bolla del blister, si rompe il foglio di chiusura； in questo modo si spezza anche il supporto adesivo e con esso il tracciato del PCB rivelatore. Il circuito viene così «aperto». Mediante i terminali del
