摘要： PURPOSE:To make an odorant sensor to be easily manufactured, to quickly respond, and to be able to use various kinds of lipids and, at the same time, to have chemical and mechanical durability by using a film made of the mixture of a high-molecular compound and lipid for the odorant molecule adsorbing film of the sensor. CONSTITUTION:A crystal resonator 11 is a piezoelectric element composed of, for example, an AT-cut quartz substrate 11a and gold electrodes 11b formed on both side faces of the substrate 11a. A film 12 of the mixture of polyvinyl chloride and dioctyl phosphate (lipid), namely, an odorant molecule adsorbing film 12 having an average film thickness of about 0.2mum is formed on the electrode 11b on one side face of the resonator 11. When the film 12 adsorbs odorant molecules, the resonance frequency of the film 12 is increased by the adsorbed amount of the molecules. As the resonance frequency of the film 12 increases, the resonance frequency of the resonator 11 decreases and, when the resonance frequency of the resonator 11 is measured, the odor can be measured. Since the mixture of the high-molecular compound and lipid is used for the film 12 in such a way, the film 12 can be manufactured by a spin coating method, etc., and even such a lipid that cannot be used for manufacturing an LB or bimolecular film can be used.

摘要： PURPOSE:To highly sensitively detect odorant by forming a thin layer of water or some kind of aqueous solution on a lipid film formed on a gate of an ion- sensitive or ion-insensitive FET. CONSTITUTION:When odor molecule in the air is solved into a layer 3 comprising water or some kind of aqueous solution of a lipid film type odor sensor 101, an odor molelcule is adsorbed by a lipid film 2 and a film structure or the like of a lipid molecule is varied so that surface potential is changed. That is, bias voltage is applied only by surface potential generated on a gate 17 of an ion-insensitive FET 1. Further the FET 1 is constantly applied by drain.source voltage and drain current. That is, the FET 1 always operates at the same operating point, and if bias voltage is applied to the gate 17, the point is shifted by a value equal to the bias voltage with voltage between a reference in voltage is output from an output terminal 106.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for detecting an odor substance capable of easily increasing amount of detection information on odor substances. SOLUTION: An electric current is supplied between a working electrode 1 and a pair electrode 2 by a potentiostat 4 so that a voltage between the working electrode 1 and a reference electrode 3 is a desired one. An oscillator 5 controls the potentiostat 4 to slightly change the desired voltage. A computer 7 calculates an impedance of the working electrode 1 from information on voltage and current changes from a digital voltmeter 6. On the basis of the impedance, the odor substance dissolved in a reference solution 8 contained in a filter paper 106 on a surface of the working electrode 1 is detected. The reference solution 8 includes at least one of solvent, a surface active agent, and a bitter substance.

摘要： PROBLEM TO BE SOLVED: To fully exhibit the function of a taste sensor for a long time by installing a through hole that is open to the fresh air at an electrode or near it, allowing gas to escape through a film for detecting taste into the fresh air through the through hole, and preventing the gas from being accumulated between the film and the electrode. SOLUTION: A cylinder made of acryl with a thickness of approximately 3 mm is used as a substrate 1. One end of the cylinder is covered with a lid 1a made of an acryl plate so that no solution to be measured enters the cylinder. A hole 2 (3 mmϕ) is punched into a substrate 1, a round rod made of silver with a through hole 6 of 1 mmϕ inserted axially into the hole 2 as an electrode 3. Terahydrofuran is dripped onto one end of the electrode 3 and an acryl plate around it as an adhesive to paste a square film 4 for detecting taste whose one side is approximately 10 mm and is prepared in advance so that the electrode 3 is covered. A lead wire 5 is soldered to the other end of the electrode 3. Gas through the film 4 for detection passes through the inside of the acryl cylinder as the substrate 1 and escapes into the fresh air. In this manner, the created taste sensor is capable of measurement for one month.

摘要： PURPOSE:To improve orienting property and endurance while enabling a non- electrolytic measurement by arranging a group of hydrophobic groups each bonded chemically to a substrate electrode to cover the entire surface thereof contacting a solution to be measured of the substrate electrode. CONSTITUTION:A functional group is introduced into the surface of a substrate electrode 1 comprising a carbon-based electrode and a metal electrode or a metal oxide semiconductor electrode. A hydrophobic group 2 of an amphipathic substance or a bitter substance for various sensors is modified using a normal organic chemical reaction so that the group of hydrophobic groups 2 is bonded 3 chemically to the substrate electrode 1 immediately. This enables the producing of a taste sensor using a monomolecular film made of the group of hydrophobic groups 2, amphipathic substance or the like having endurance, excellent orienting propery and limited variations in quality and moreover, a sensor highly sensitive to non-electrolyte such as sugar.
