Summary

Summary: 
A Spanish university has developed a device to create a visual code in which the information stored can vary dynamically depending on physicochemical parameters. This can be used in medicine to offer rapid diagnoses, in the food industry to assess the status and quality of the product or for color calibration in printing. The university is looking for companies related to the development of smart packaging for medical and/or food industries or in vitro diagnostic tests, interested in licensing.

Description

Description: 

Today visual codes like the QR ("Quick Response") codes are everywhere: printed on the packaging, on business cards or included on presentations at conferences. Companies use them to store and distribute all kinds of information in a manner that is quickly accessible to anyone with a smartphone.

A Spanish university has developed a device 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.

The university is looking for partners from companies related to the development of smart packaging for medical and/or food industries, as well as companies that develop in vitro diagnostic tests, interested in licensing this technology.

Advantages & innovations

Cooperation plus value: 
- 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. - Multiple applications. Because of the dynamic layer versatility, the code 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
