    PVDF PIEZO film


    Piezoelectric film


    piezoelectric sensor

    PVDF PIEZO sensor, PVDF PIEZO transducer ,PVDF PIEZOelectric sensor


    1.Piezoelectric property

    It produces voltage in proportional to compressive or tensile mechanical stress or strain, which makes it a dynamic strain gauge.

    2.Dielectric property and low impedance

    Piezo film changes proportionally in dimension while an electric field at frequencies from 0~500MHz. This property, as well as the film’s low impedance, makes piezo film perfectly suitable for high fidelity transducers operation throughout the high audio and ultrasonic.

    3.pyroelectric property

    piezo filmalso reactsto changes in temperature with predictable, high voltage outputs

    4.Chemically insert and biocompatible.

    It is ideally to make vital signs transducer attached to skin or be used in medical devices.

    5.high stress constant

    Piezo film’s stress constant is about 10 times higher than other piezoelectric materials

    6.excellent processibility

    thin with low weight and low mass, can be twisted into various forms.

    7.Low temperature property

    It works in the temperature as low as-40°C.
