PVDF PIEZO film, PIEZO film ,PVDF PIEZO membrane,PVDF PIEZO sensor

Characteristics

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 such as ceramics and quartz.

6.excellent processibility

It is thin with low weight and low mass, so it can be twisted into various forms.

7.Low temperature property

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