Portable electronic tongue, taste fingerprint analyzer
1、 Introduction to electronic tongue (taste fingerprint analysis):
Electronic tongue (taste fingerprint analysis) is a modern qualitative and quantitative analysis and detection instrument mainly composed of interactive sensitive sensor array, signal acquisition circuit and data processing method based on pattern recognition
Based on the stable sensor array composed of inert metal electrodes, the original idea of combined pulse relaxation spectrum is realized by voltammetric electrochemical pulse technology, and then the overall information of the measurement object is obtained by AC mutual inductance stress analysis technology

Based on the independently developed electronic circuit hardware and computer intelligent algorithm software, c-tougue is developed, which can realize fast, real-time and online overall product feature evaluation and rapid qualitative and quantitative detection and analysis of some components
It can measure the acid, sweet, bitter, spicy and fresh taste of food and medicine

2、 Structural features:
1
The system has a wide range of applications (solution, powder, aqueous solution, organic solution, etc
)
2
Fast detection speed (1-3 minutes)
3
Large amount of response spectrum information (high resolution)
4
Long service life of sensor (more than 10 years)
5
Fast cleaning (1-2 minutes)
6
Suitable for intellectualization and miniaturization
7
Data processing algorithms are diverse, including dimensionality reduction, classification, regression and clustering data analysis, including PCA, LDA, BP neural network, SVM and other algorithms
