THIN FILM PIEZO SPEAKER
Polyvinylidene Fluoride Piezoelectric Film (PVDF) is a relatively new class of piezo-electric device. PVDF material is a thin plastic polymer sheet with its molecules aligned in a uniform pattern. It has a electrically conductive coating deposited on each side of the sheet. To use PVDF material, an electrical connection to these conductive coatings is needed. Soldering directly to the film is not possible because the heat would destroy the underlying plastic PVDF material. This limitation is overcome by printing a conductive layer of ink around the edge of each side of the speaker film. Like all high-tech materials, this requires specialized manufacturing processes and the reason for this Kickstarter campaign.
This new form of material resembles thick sandwich wrap but has much more interesting properties
AMAZING PIEZO-FILM PROPERTIES
Piezo film has an extremely high output potential, about 10 times greater than ceramic materials. Since the material is a thin, light weight, flexible film it can be glued onto shaped designs. The material has a high mechanical strength and is impact resistant.
Other attributes include:
- Wide Frequency Range. (.001 Hz – 10 GHz)
- Low acoustical impedance (matching water or human tissue)
- High dielectric strength.
- Good mechanical durability.
- Moisture resistant.
- Inert to many chemicals.

An incredible new technology has led to the development of potentially some of the thinnest speakers in the world. They are wide, flat and very flexible.
At only 0.25mm thick, the material is both lightweight and very inexpensive to manufacture. Speakers made out of this material could be used in cars, in homes, in ceiling tiles and even made into posters or pictures that hang on the wall.
Because of its large, flat surface area, the speakers produce sound waves that are planar and directional and can project further than normal speakers. This means that they could be very useful in airports or passenger terminals where conventional speakers can be very hard to hear.
The first commercial speakers using the technology are expected to launch later this year. I’m imagining gig posters that play the music of the band when I walk by them, wearable speakers and shower curtains that play music!
