Acoustic Wave Application for the Analysis of the Quality & Safety of Porous Food & Non-food Systems


A quick method for the detection of mycotoxins in grains and an acoustic device for the evaluation of the quality of porous food systems in production.


ACOUSTICS project outcomes – the project has proved the usability of the acoustic method both by acoustic wave transition and by reflection in the creation of a quick and cheap method for the detection of the following mycotoxins: (i) deoxynivalenol (DON) in wheat and (ii) aflatoxin (AFT) in corn, as well as (iii) the evaluation of the structure/texture of porous food matrices, such as bread, biscuits, extruded products, and/or their changes during storage.

Specific knowledge gained during the ACOUSTICS project allowed to create specialized software which was installed during the implementation of the acoustic device prototype.

Empathic (ITEA 2~11005) project: “EMPATHIC PRODUCTS”


An empathic application that  recognizes consumer preferences based on a combination of emotional, behavioural and sensory information; provides more effective feedback from consumers about their food choices and helps to improve customer interaction with its consumers; and gives additional helpful information about food products.


EMPATHIC project outcomes:

  • Methodology for empathic (intentional & emotion enabled) applications in food market was created;
  • New models for exploiting sensory attributes & intention & emotion awareness of food consumers was formed;
  • Emotion & intention enabling technologies tested & validated in food market: baking and confectionary industries.

Study showed that Noldus FaceReader technology is sufficiently accurate to detect significant differences in facial expressions elicited by different food samples and can deliver additional information to conventional acceptance tests. The correlations obtained show that facial expressions are good indicators for self-reported liking.  Furthermore, emotions, attitude and behaviour interface model was designed, which can give a significant information about food products evaluation and food choice. Strong relationship between attitude and behaviour was also observed.

Determination of Position with the Help of Accelerometers


Supervision of residents of intelligent households, visitors of health care organisations, sports facilities usually requires the determination and evaluation of their body position.

Body position is determined with the help of two accelerometers, transferring coordinates of three vectors to the computer via wireless connection.

One accelerometer is placed on a chest, the other – on a hip. Static and dynamic positions are determined.

The intelligent household system can recognise position of a body and, if it is needed, will call the help automatically.

Electronic Device for Soil Humidity Measurement


A working prototype for humidity measurement, designed in real conditions, allowing to measure soil humidity with less than 10% error.

The research was performed with different soil types, whose electric characteristics were measured by using a finite element method, simulated and optimized using interlocked electrode sensors and chip AD5933 for impedance measurement.

The developed device will help to identify clay-type soils by the humidity parameter, with reference to the quantitative index of this parameter. This is relevant for clay-type soils with higher humidity.
