3.2Types of chemical and biochemical sensors3.2.1

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.

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

4 Specifications

4.1General

Chemical and biochemical sensors are used in various applications，for example，in thedetection of target molecules/substances,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.
