Title:
VOLATILE FATTY ACID DETECTION SENSOR, VOLATILE FATTY ACID DETECTION DEVICE, AND METHOD FOR MANUFACTURING VOLATILE FATTY ACID DETECTION SENSOR
Document Type and Number:
WIPO Patent Application WO/2023/058539
Kind Code:
A1
Abstract:
The present invention provides a small sensor for detecting volatile fatty acids with high sensitivity. A volatile fatty acid detection sensor according to one embodiment of the present invention includes a quartz vibrator, a first electrode formed on a first main surface of the quartz resonator, and a second electrode formed on a second main surface of the quartz vibrator. A substance, which adsorbs a different amount of water from a gas phase according to the amount of volatile organic acid in the gas phase, is implanted in at least one surface of the first electrode and the second electrode, and volatile fatty acids are detected by changes in the frequency of the quartz vibrator.
