PVDF High Sensitive Plastic Film Piezo Sensors

PVDF high sensitive plastic film piezo sensors      Polyvinylidene fluoride (PVDF) piezoelectric film is a new kind of polymer piezoelectric material which was developed in Japan in the 1970s. So far, only a few advanced countries in the world have produced it. It has unique dielectric effect, piezoelectric effect and thermoelectric effect. Compared with traditional piezoelectric materials, it has the advantages of wide frequency response, large dynamic range, high sensitivity of power-electric conversion, high mechanical strength, easy matching of acoustic impedance, light weight, soft and not brittle, impact resistance, not easily contaminated by water and chemicals, and easy to be made into pieces or tubes of different shapes and areas. It is widely used in mechanics, acoustics, optics, electronics, measurement, infrared, security alarm, medical care, military, traffic, information engineering, office automation, Marine development, geological exploration and ot…
