Abstract

Embodiments of the invention include an apparatus, a computer-implemented method, and a computer program product for branding a quick response code onto a surface. Aspects of the invention include a branding device having a plurality of thermoelectric devices on a substrate. Each of the thermoelectric devices is arranged on the substrate as a single bit in a quick response pattern. Each of the thermoelectric devices includes an n-type thermoelectric element electrically coupled to a p-type thermoelectric element. The thermoelectric elements can be individually heated or cooled using the Peltier effect.

First claim

What is claimed is:

1. An apparatus comprising:
a plurality of thermoelectric devices on a substrate, each of the thermoelectric devices arranged on the substrate as a single bit in a linear or matrix barcode pattern;
wherein each of the thermoelectric devices comprises an n-type thermoelectric element electrically coupled to a p-type thermoelectric element.

2. The apparatus of claim 1 , wherein the linear or matrix barcode pattern is a quick response pattern or a DataMatrix pattern.

3. The apparatus of claim 2 , wherein the quick response pattern is a quick response (QR) Version 1 to Version 40 pattern, an iQR pattern, or a micro QR pattern.

4. The apparatus of claim 1 , wherein each of the thermoelectric devices comprises two or more pairs of thermoelectric elements, each pair comprising an n-type thermoelectric element electrically coupled to a p-type thermoelectric element.

5. The apparatus of claim 1 , wherein each of the thermoelectric devices further comprises a contact surface coupled to an end of the n-type and p-type thermoelectric elements.

6. The apparatus of claim 5 , wherein each contact surface comprises a rectangular or superelliptical shape.

7. The apparatus of claim 1 further comprising a plurality of electrodes formed on a surface of the substrate, each electrode electrically coupled to a thermoelectric device of the plurality of thermoelectric devices.

8. The apparatus of claim 7 further comprising a plurality of vias in the substrate, each via electrically coupling an electrode to a thermoelectric device.

9. The apparatus of claim 1 , wherein the linear or matrix barcode pattern comprises a high resolution grid.

10. A computer-implemented method for branding a quick response code onto a surface, the method comprising:
receiving, by a processor, data to be encoded into the quick response code;
generating, by the processor, the quick response code that encodes the data;
determining, by the processor, a first subset of thermoelectric devices of a quick response branding device to heat to generate the quick response code; and
sending, by the processor, program instructions to heat the first subset of thermoelectric devices to the quick response branding device.

11. The computer-implemented method of claim 10 further comprising determining, by the processor, a second subset of thermoelectric devices of the quick response branding device to cool to generate the quick response code.

12. The computer-implemented method of claim 11 further comprising sending, by the processor, program instructions to cool the second subset of thermoelectric devices to the quick response branding device.

13. The computer-implemented method of claim 11 , wherein the first subset of thermoelectric devices is heated while the second subset of thermoelectric devices is cooled.

14. The computer-implemented method of claim 10 , wherein the quick response code is a quick response (QR) Version 1 to Version 40 pattern, an iQR pattern, or a micro QR pattern.

15. The computer-implemented method of claim 10 further comprising determining, by the processor, a second subset of thermoelectric devices of the quick response branding device to heat to generate the quick response code.

16. The computer-implemented method of claim 15 further comprising sending, by the processor, program instructions to heat the second subset of thermoelectric devices to the quick response branding device.

17. A computer program product for branding a quick response code onto a surface, the computer program product comprising:
a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processing device to cause the processing device to perform a method comprising:
receiving data to be encoded into the quick response code;
generating the quick response code that encodes the data;
determining a first subset of thermoelectric devices of a quick response branding device to heat to generate the quick response code; and
sending program instructions to heat the first subset of thermoelectric devices to the quick response branding device.

18. The computer program product of claim 17 further comprising determining a second subset of thermoelectric devices of the quick response branding device to cool to generate the quick response code.

19. The computer program product of claim 18 further comprising sending program instructions to cool the second subset of thermoelectric devices to the quick response branding device.

20. The computer program product of claim 19 , wherein the first subset of thermoelectric devices is heated while the second subset of thermoelectric devices is cooled.
