Tutorial and Hands-on Training On Electronic Nose, Tongue and Vision Systems

December 18, 2012


  • Introduction to the course program
  • Basic Science for designing E-Nose, E-Vision and E-Tongue Technologies
  • Digital camera and image processing fundamentals
  • Different sensors for the systems
  • Applications of the Electronic Nose, Tongue and Vision systems
  • GUI development using LabVIEW
  • Hands-on training & demonstration

Electronic Nose

Electronic Nose is an instrument that comprises of an array of gas sensor and suitable pattern recognition model. When a volatile compound comes in the contact of these sensors surface, resistance of the sensor changes. These changes in resistance is measured and a pattern recognition engine looks for the specific pattern in the sensor array generated series of patterns out of the volatile compounds for assessment of different samples.

Electronic Vision

Electronic Vision is a specific digital camera-based solution for objective assessment of quality or identification of some objects. Electronic vision system consists of a camera with proper illumination arrangement and image processing based analysis software.

Electronic Tongue

Electronic Tongue is an instrument that comprises of noble metal based electrode array and works on voltammetric technique. In the instrument, a specified voltage is applied between working electrode and counter electrode and the voltage equivalent of output current from working and reference electrode is acquired through the data acquisition card, where it is collected and stored for data analysis.

Application of these technologies

  • Electronic Nose for Environmental Monitoring.
  • Electronic Nose for Food Industry.
  • Electronic Nose for Pharmaceutical Industries.
  • Electronic Vision for Food Industry.
  • Electronic Vision for Colour characterisation of different products.
  • Electronic Tongue for analyze flavor ageing in beverages.
  • Electronic Tongue for quantifies bitterness or “spicy level” of drinks or dissolved compounds.
  • Electronic Tongue for quantify taste masking efficiency of formulations (tablets, syrups, powders, capsules, lozenges).
  • Electronic Tongue for analysing medicines stability in terms of taste.
