3.2 Types of chemical and biochemical sensors
3.2.1 piezoelectric chemical sensor element piezoelectric sensor component including a sensitive layer (target recognition material), whichis necessary for the practical measurement of simple non-biological molecules in quantity,and which works and detects chemical substances mainly in the gas phase
Note 1 to entry: For example, there are odour sensors, vapour sensors, smoke sensors, etc.[SOURCE: IEC 63041-1:2017, 3.3.1,modified – Note 1 to entry has been added.]
3.2.2 piezoelectric biochemical sensor element piezoelectric sensor component including a receptive layer (target recognition material), whichis necessary for the practical measurement of complex biological molecules in quantity, andwhich works mainly in aqueous media and detects biomolecules therein [SOURCE:IEC 63041-1:2017,3.3.2]
4 Specifications
4.1 General
Chemical and biochemical sensors are used in various applications， for example,in thedetection of target moleculeslsubstances，the detection of growth,decrease, differentiationand cohesion in cells，the detection of adsorption or absorption，the confirmation of thecompetition reaction, etc. Concepts and specifications for chemical and biochemical sensorsare shown in detail in 4.2 to 4.5.
