要約(英語): The complex dielectric constant of a polymer piezoelectric sensor was measured to investigate the properties of biopolymers detection of piezoelectric polymer using relaxation behavior. From the measurement of the complex permittivity, relaxation of the polymer piezoelectric sensor was confirmed. In the properties of the detection of the polymer film, the real part (ε') of the relaxation process linearly shifted to the low frequency with loading the polymer films. This showed the same trend as the result that the frequency shifted to the low frequency with loading mass anticipated from Sauerbrey's equation. In the biopolymer detection, the relaxation was shifted to the low frequency with the fluorescently labeled avidin (the host material) immersion time. With accompanying fluorescently labeled biotin (the guest material) adsorption by host-guest reaction, the relaxation shifted to low frequency. It was considered that the biopolymer detection with the polymer piezoelectric sensor is possible by using relaxation behavior.
