a thermoformed, vacuum-formed, folded or otherwise formed electrically insulating sheet-like body having a number of cavities extruded from the surface of the body;
a lidding film layer which closes the openings of said cavities on said formed electrically insulating sheet-like body, wherein said lidding film layer contains one or more electrically conductive regions;
an electronic circuit with two or more electrical connections to at least one of said electrically conductive regions, arranged to provide wireless electronic communication with an external RFID reader device; and
at least one sensor coupled to said electronic circuit.
2. The blister package of claim 1 wherein said sensor is a tamper detection sensor.
3. The blister package of claim 1 wherein said sensor is a temperature sensor.
4. The blister package of claim 1 wherein said sensor is a humidity sensor.
5. The blister package of claim 1 wherein said sensor is a pressure sensor.
6. The blister package of claim 1 wherein said sensor is a chemical sensor.
7. The blister package of claim 1 wherein said sensor is a light sensor.
8. The blister package of claim 1 further comprising a memory coupled to said electronic circuit and arranged to store data.
9. The blister package of claim 1 wherein said electronic circuit further comprises a monitoring circuit configured to detect changes in sensor data.
10. The blister package of claim 1 wherein said electronic circuit is configured to achieve wireless electronic communication with an external RFID reader device in accordance with the Near Field Communication (NFC) international standards.
11. A blister package lidding layer for a blister package with integrated sensor and electronic tag wherein said blister package comprises one or more cavities, each cavity configured to contain an item, said lidding layer comprising
a lidding film for closing the openings of said cavities, wherein said lidding film contains one or more electrically conductive regions;
an electronic circuit with two or more electrical connections to at least one of said electrically conductive regions, arranged to provide wireless electronic communication with an external RFID reader device; and
at least one sensor coupled to said electronic circuit.
12. The blister package lidding layer of claim 11 wherein said sensor is a tamper detection sensor.
13. The blister package lidding layer of claim 11 wherein said sensor is a temperature sensor.
14. The blister package lidding layer of claim 11 wherein said sensor is a humidity sensor.
15. The blister package lidding layer of claim 11 wherein said sensor is a pressure sensor.
16. The blister package lidding layer of claim 11 wherein said sensor is a chemical sensor.
17. The blister package lidding layer of claim 11 wherein said sensor is a light sensor.
18. The blister package lidding layer of claim 11 further comprising a memory coupled to said electronic circuit and arranged to store data from said sensor.
19. The blister package lidding layer of claim 11 wherein said electronic circuit further comprises a monitoring circuit configured to detect changes in sensor data.
20. The blister package lidding layer of claim 11 wherein said electronic circuit is configured to achieve wireless electronic communication with an external RFID reader device in accordance with the Near Field Communication (NFC) international standards.
21. A blister package lidding layer for a blister package with integrated electronic tag wherein said blister package comprises one or more cavities, each cavity configured to contain an item, said lidding layer comprising
a lidding film for closing the openings of said cavities, wherein said lidding film contains one or more electrically conductive regions;
a printed electronic circuit with two or more electrical connections to at least one of said electrically conductive regions, arranged to provide wireless electronic communication with an external RFID reader device.
22. The blister package lidding layer of claim 21 further comprising at least one sensor coupled to said electronic circuit.
