Summary of the technology
A new visual code (QR, barcode, etc.) has been developed in which the information stored can vary dynamically depending on physicochemical parameters.
This device has application in different sectors of analysis and storage of information (in medicine to offer rapid diagnoses, in the food industry to assess the status and quality of the product, for color calibration in printing, among others).
Details of the Technology Offer
It has been patented a process to create visual codes (e.g., QR code) made up of overlapping layers of information: a static information layer with a fixed graphic impression, and one or more dynamic information layers with a changing graphic impression.
For making smart sensors, the dynamic layers contain some chemical and/or biochemical compounds (such as enzymes or antibodies). These compounds produce colorimetric changes depending on the environmental conditions or the presence of external agents.
Upon optical recognition of the visual code, if a color change occurs in the dynamic layer, an error is generated that is detected by the error correction algorithm and interpreted with a predetermined meaning. In this way, the device makes it possible to interpret and provide information according to whether external chemical or biological agents are detected.
ADVANTAGES AND BENEFITS
- Compatible with common decoding.Visual codes maintain the size and appearance of a common visual code.
- The dynamic layer increases the capacity and functionality of the code.Common visual code decoding procedures have very rigid reading conditions. Patented devices have dynamic layers of information that modify the original code and are interpreted as useful information.
- Quick analysis of information.
- Multiple applications.Because of the dynamic layer versatility, the device can be used for different purposes depending on its configuration. Among its applications are:
- Creation of smart food packaging
- Diagnosis of diseases
- Pregnancy test
- Colorimetric calibration
