    摘要： A multi-channel drug detection method is proposed. The method may include inputting an electrical signal of a frequency included in a search range set in sensors of a sensor board, comparing magnitudes of electrical signals output by the sensors, and determining a frequency having the largest magnitude as a resonance frequency, the inputting, comparing, and determining being repeatedly performed. The method may also include determining, as a first resonance frequency, a resonance frequency determined in the inputting, comparing, and determining performed before a sample is inserted, and inserting the sample into the sensor board. The method may further include determining a second resonance frequency by repeating the inputting, comparing, and determining while moving the search range to search for a resonance frequency. The method may further include determining presence of a target material based on a difference between the first resonance frequency and the second resonance frequency.

    摘要： A sensor apparatus includes: an element substrate; a detecting section disposed on an upper surface of the element substrate, the detecting section including a reaction section having an immobilization film to detect an analyte; a first IDT electrode configured to generate an acoustic wave which propagates toward the reaction section, and a second IDT electrode configured to receive the acoustic wave which has passed through the reaction section; and a protective film located on the upper surface of the element substrate so as to cover the first IDT electrode, the second IDT electrode, and at least part of the immobilization film, the protective film extending between and contacting with the immobilization film and at least one of the first IDT electrode and the second IDT electrode.

    摘要： A method of making an acoustic wave sensor includes the steps of providing a piezoelectric substrate layer and printing on the substrate layer a sensor layer comprising a first interdigitated acoustic wave transducer, a sensing film, and positioned on an opposing side of the sensing film from the first interdigitated acoustic wave transducer at least one selected from the group consisting of a second interdigitated acoustic wave transducer and a Bragg reflector. An insulation layer can be printed. An antenna can be printed in an antenna layer, and the insulation layer can be interposed between the antenna layer and the sensor layer. An electrical connection can be printed between the antenna and the first interdigitated acoustic wave transducer. An acoustic wave sensor is also disclosed.
