PVDF piezoelectric film 15-500um
General Introduction :PVDF Piezoelectric flouropolymer film or piezo film is a kind of fresh high polymer piezoelectric material .Till now ,only a few countries can produce this kind of film in the world.
Our products are available in a variety of different sizes, thickness and metallization options for OEM manufacturing. Piezo film is an excellent transducer with unique capabilities.
PVDF has the unique effect of the dielectric, piezoelectric effect, the thermoelectric effect.Compared with the conventional piezoelectric materials with wide frequency response, dynamic range, high sensitivity electromechanical conversion and mechanical properties of high strength, acoustic impedance matching, and has a light weight, soft, not brittle, impact resistant, less susceptible to water and chemical pollution,easily made into any shape and size, ranging from plates or tubes advantage.
A wide range of applications in mechanics, acoustics, optics, electronics, measurement, infrared, security alarm, health care, military, transportation, information engineering, office automation, marine development, geological exploration and other technical fields. The products have mainly three varieties of gold, silver, aluminum, thickness 30-500um. Product shape and size can be determined according to user’s needs.It is the new transducer materials to produce improvements Dynamic Pressure sensors and ultrasound, intelligent exploration .
Ⅱ 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 film also reacts to 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 quartzhigh chemical stability.
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℃
Performance and Characteristics:
PVDF piezoelectric film has a high chemical stability, low moisture absorption, high thermal stability, high resistance to UV
radiation capacity, high impact resistance, fatigue resistance capacity, and its chemical stability is 10 times higher than the ceramic,. It can be used at the temperature bellow80 ℃ long-term . PVDF piezoelectric film texture is soft, light weight, with similar acoustic impedance of water, matching well, application of high sensitivity; PVDF piezoelectric film has high stretching vibration of the harmonic frequency in the thickness direction , you can get a wide flat response.Its frequency response width is far superior to the ordinary piezoelectric ceramic transducer; high capacitance
PVDF piezoelectric film’s advantages:
(1) good manufacturability . Existing equipment is available for processing;
(2) It can be made into large area sensitive element;
(3) The band respond to a wide (500MHz);
(4) Acoustic impedance closes to human tissue and water, and so it can be used for the structure of sensitive medical diagnostic devices;
(5) High impact strength (enable sensors for shock wave);
(6) Corrosion resistance (Using this performance in the active medium is required );
(7) Lower relative dielectric constant; corresponding high piezoelectric constant value d 33 (one or more order of magnitude than other piezoelectric materials) and thermal signal sensitivity (p / ε) values;
(8) Lower thermal conductivity than piezoelectric ceramic , and even thinner film;
(9) Soft and tough ( PVDF’s supple coefficient is about 30 times of that of PzT and light (specific gravity is only about 1/4 of PzT). It can be made into a variety of complex shapes (cone, dome-shaped, etc.),it can be used in the components which need to have a special orientation.
Overall: PVDF piezoelectric film has a large piezoelectric constant, wide frequency response, good mechanical strength, impact resistance, light weight, flexible, easy to match the acoustic impedance than quartz, PZT, easy to process into big area products, less susceptible to water and general chemical pollution, the price is cheap. It is not only alternative in many areas of piezoelectric ceramic materials, but also can be applied to the occasion where the piezoelectric ceramic materials can not use.
Therefore, it is an extremely promising transducer sensitive polymer materials.
