Abstract

A wireless (e.g., near field or RF) communication device, and methods of manufacturing and using the same are disclosed. The wireless communication device includes a receiver and/or transmitter, a substrate with an antenna thereon, an integrated circuit, and one or more continuity sensors. The antenna receives and/or transmits or broadcasts a wireless signal. The integrated circuit processes the wireless signal and/or information therefrom, and/or generates the wireless signal and/or information therefor. The continuity sensor(s) are configured to sense or determine the presence of a chemical or substance in the package or container, and thus a continuity state of a package or container on which the communication device is placed or to which the communication device is fixed or adhered. The continuity sensor(s) are electrically connected to a set of terminals of the integrated circuit different from the set of terminals to which the antenna is electrically connected.

Claims

1. A wireless communication device, comprising:

a) a receiver and/or transmitter;

b) a substrate with an antenna thereon, said antenna receiving a first wireless signal and/or transmitting or broadcasting a second wireless signal;

c) an integrated circuit configured to (i) process said first wireless signal and/or information therefrom, and/or (ii) generate said second wireless signal and/or information therefor, said integrated circuit having a first set of terminals electrically connected to said antenna; and

d) one or more continuity sensors on a common or different substrate, the continuity sensor(s) comprising (i) a chemical sensor configured to sense or determine a presence of material in a package or container on which the communication device is placed or to which the communication device is fixed or adhered, and (ii) a trace electrically connecting the chemical sensor to a second terminal of said integrated circuit different from said first set of terminals.

2. The wireless communication device of claim 1, wherein the continuity sensor(s) comprise a trace with a section therein including a material having a conductance or resistivity that changes based on exposure to a chemical or substance inside the package or container.

3. The wireless communication device of claim 1, wherein the continuity sensor(s) comprise a transistor with a gate or base including a material having a conductance or resistivity that changes based on exposure to a chemical or substance inside the package or container.

4. The wireless communication device of claim 1, wherein the integrated circuit further comprises a second sensor electrically connected to said integrated circuit at a third set of terminals different from said first and second sets of terminals.

5. The wireless communication device of claim 1, wherein the integrated circuit further comprises a memory including one or more bits configured to store a value corresponding to a continuity state of the container or package.

6. The wireless communication device of claim 5, wherein the memory includes a plurality of bits configured to store a unique identification code for the container or package.

7. The wireless communication device of claim 1, further comprising one or more redundant continuity sensors.

8. The wireless communication device of claim 1, wherein said substrate comprises a plate, disc and/or sheet of a glass, ceramic, dielectric and/or plastic.

9. A package or container, comprising:

a) first and second separable parts with an interface therebetween; and

b) the wireless communication device of claim 1, on one of the first and second separable parts of the package or container, wherein the continuity sensor(s) is near the interface.

10. The package or container of claim 9, wherein the continuity sensor(s) is configured to determine a presence of a chemical or substance in the package or container.

11. The package or container of claim 10, wherein the package or container is considered open when the continuity sensor(s) determines the presence of the chemical or substance, and the package or container is considered sealed when the continuity sensor(s) does not determine the presence of the chemical or substance.

12. A method of manufacturing a wireless communication device, comprising:

a) forming an antenna on a first substrate, said antenna being configured to receive and/or transmit or broadcast a wireless signal;

b) forming one or more continuity sensors on a common or different substrate;

c) forming an integrated circuit on a substrate common with at least one of the antenna and the continuity sensor(s), or different from each of the antenna and the continuity sensor(s); and

d) electrically connecting the antenna to a first set of terminals of the integrated circuit, and the continuity sensor(s) to a second set of terminals of the integrated circuit.

13. The method of claim 12, further comprising forming a trace in the continuity sensor(s), the trace having a section therein including a material having a conductance or resistivity that changes based on exposure to a chemical or substance inside the package or container.

17. The method of claim 12, wherein forming the integrated circuit further comprises forming a memory including (i) one or more bits configured to store a value corresponding to a continuity state of the container or package and (ii) a plurality of bits configured to store a unique identification code for the container or package.

18. A method of detecting an opened package or container, comprising:

a) placing a wireless communication device comprising an antenna, one or more continuity sensors, and an integrated circuit electrically connected to each of the antenna and the continuity sensor(s) on the package or container such that at least one of the continuity sensor(s) is near an interface between first and second separable parts of the package or container; and

b) using the integrated circuit and the at least one continuity sensor, sensing a continuity state of the package or container.

19. The method of claim 18, wherein the continuity sensor(s) comprises a trace having a section therein including a material having a conductance or resistivity that changes based on exposure to a chemical or substance inside the package or container.

20. The method of claim 19, wherein the continuity state of the package or container is opened when the continuity sensor(s) determine a presence of a chemical or substance in the package or container, and the continuity state of the package or container is closed or sealed when the continuity sensor(s) does not determine the presence of the chemical or substance.
