Abstract

Systems, devices, admixtures, and methods are described including transponder devices (e.g., a palatable transponder, an edible transponder, a palatable radio frequency identification (RFID) tag, an edible RFID tag, etc.) for admixing with a food product.

First claim

What is claimed is:

1. An apparatus, comprising:
an interrogation interface;
a food-attribute-identification circuit coupled to the interrogation interface, configured to store food-attribute data associated with a food product having a permittivity, and configured to provide, before the food-attribute-identification circuit is consumed, the food-attribute data in response to the interrogation interface;
an antenna coupled to the interrogation interface and configured for sensitivity at a frequency range that is a function of the permittivity of the food product; and
an encapsulant not including the food product, disposed over the interrogation interface, the food-attribute-identification circuit, and the antenna, configured for admixing with the food product, and having one or more organoleptic attributes that mimic the food product.

2. The apparatus of claim 1 , wherein the encapsulant includes an elastomer configured to reduce human sensory feedback when the integrated circuit is in a human dental occlusion.

3. The apparatus of claim 1 , wherein the interrogation interface includes the antenna, and wherein the antenna includes an edible wire antenna.

4. The apparatus of claim 1 , wherein the interrogation interface includes the antenna, and wherein the antenna has a cross-section on the order of tens of micrometers.

5. The apparatus of claim 1 , wherein the interrogation interface includes the antenna, and wherein the antenna has a cross-section on the order of hundreds of micrometers.

6. The apparatus of claim 1 , wherein the interrogation interface includes the antenna, and wherein the antenna has a cross-section ranging from about tens of micrometers to about hundreds of micrometers.

7. The apparatus of claim 1 , wherein the interrogation interface includes the antenna, and wherein the antenna has a rigidity that is substantially the same as that of the food product.

8. The apparatus of claim 1 configured to self-tune.

9. The apparatus of claim 1 configured to self-tune to compensate for environmental effects.

10. The apparatus of claim 1 configured to self-tune to compensate for encapsulant materials effect.

11. The apparatus of claim 1 , further comprising one or more tunable transistors to self-correct for changes in temperature.

12. An apparatus, comprising:
a palatable substrate having at least one electrical trace and having one or more organoleptic attributes that mimic a food product, the palatable substrate being distinct from the food product and being configured to be admixed with the food product, the palatable substrate having a dielectric constant;
an integrated circuit disposed on the substrate;
an interrogation interface disposed on the substrate, coupled to the at least one electrical trace, and configured to provide information about the food product to a location remote from the palatable substrate while the palatable substrate is mixed with the food product but before the palatable substrate is consumed; and
an antenna disposed on the palatable substrate, coupled to the interrogation interface, and configured to self-compensate for the dielectric constant of the palatable substrate.

13. The apparatus of claim 12 , wherein the substrate includes chamfered or rounded edges having a profile configured to reduce an incidence rate of abrasion, cutting, or lodging in the human digestive tract.

14. The apparatus of claim 12 , wherein the substrate includes one or more organoleptic attributes that reduce an ability of a person to discriminate between the palatable transponder and the food product.

15. The apparatus of claim 12 , wherein the substrate includes one or more pigments that mimic a color associated with the food product.

16. The apparatus of claim 12 , wherein the substrate includes one or more binders, fillers, gelling agents, plasticizers, stabilizers, suspending agents, or thickeners that mimic a density associated with the food product.

17. The apparatus of claim 12 , wherein the substrate includes one or more flavorants that mimic a flavor associated with the food product.

18. The apparatus of claim 12 , wherein the substrate includes one or more aromatizers that mimic a scent associated with the food product.

19. The apparatus of claim 12 , wherein the substrate includes one or more texturizers that mimic a texture associated with the food product.

20. The apparatus of claim 12 , wherein the substrate includes an edible material.

21. The apparatus of claim 12 , further comprising an elastomeric package in which the substrate is at least partially embedded, the elastomeric package including one or more materials that reduce human sensory feedback when the substrate is in a human dental occlusion.

22. A method, comprising:
configuring an integrated circuit to obtain attributes of a food product while the integrated circuit is mixed with the food product and before the food product is consumed, the food product having a permittivity;
configuring an antenna coupled to the integrated circuit in response to the permittivity of the food product; and
encapsulating the integrated circuit in an encapsulant having one or more organoleptic attributes that mimic the food product, the encapsulant not including the food product.

23. A method, comprising:
obtaining food-attribute information in response to a food product with an edible transponder device while the edible transponder device is mixed with the food product, the edible transponder device having a dielectric constant and having one or more organoleptic properties that mimic one or more organoleptic properties of the food product, the edible transponder not including the food product;
compensating an antenna disposed on the edible transponder device in response to the dielectric constant of the edible transponder device; and
transmitting, via the antenna, the food-attribute information to a destination that is remote from the edible transponder device before the edible transponder device is eaten.

24. The method of claim 23 , further comprising storing the food-attribute information on the edible transponder device.

25. A method, comprising:
acquiring, before a food is eaten, data related to the food, with a radio frequency identification tag that is admixed with the food, that has one or more organoleptic properties that respectively correspond to one or more organoleptic properties of the food, and that is distinct from the food, which has a permittivity;
configuring an antenna disposed on the radio frequency identification tag in response to the permittivity of the food; and
transmitting, via the antenna, the data in response to an interrogation request.

26. The method of claim 25 wherein the data is related to at least one of a nutritional value of the food, a nutritional value per unit volume of the food, a nutritional value per unit weight of the food, a nutritional value per unit serving of the food, a percentage of recommended daily allowance per unit volume of the food, a percentage of recommended daily allowance per unit weight of the food, or a percentage of recommended daily allowance per serving of the food.

27. The method of claim 25 wherein the data is related to at least one of a protein content of the food, a carbohydrate content of the food, a vitamin content of the food, a mineral content of the food, a calorie content of the food, or an ingredient of the food.
