Title:
ODOR DETECTION ELEMENT
Document Type and Number:
Japanese Patent JP2023111621
Kind Code:
A
Abstract:
To provide an odor detection element capable of performing an output in which influence by frequency-temperature characteristics of a sensitive film is suppressed.SOLUTION: An odor detection element according to the present invention includes a piezoelectric vibrator and a sensitive film. The piezoelectric vibrator includes: a piezoelectric layer containing a piezoelectric material as a main component; and a pair of electrodes provided in the piezoelectric layer. The sensitive film includes: a base layer provided on the piezoelectric vibrator and having positive or negative frequency-temperature characteristics; and an adsorption layer provided on the base layer and having frequency-temperature characteristics opposite to those of the base layer.SELECTED DRAWING: Figure 1
