basic information
Piezo film is a polymer piezoelectric and pyroelectric film developed using KF polymer, a polyvinylidene fluoride resin, by Kureha Corporation. Its features are: 1. Being a polymer film, it is thin, lightweight, and flexible. ⇒ Available in four thicknesses: 28μm, 40μm, 80μm, and 110μm. 2. Compared to inorganic piezoelectric materials, it has a low relative permittivity (ε’=13), demonstrating a high piezoelectric g constant (g31= 0.22 Vm/N). ⇒ Suitable for sensor applications. 3. The acoustic impedance is close to that of water. ⇒ Suitable for hydrophones and ultrasonic probes. 4. It does not exhibit strong resonance, meaning it has a low Q value, resulting in a wide response frequency range. ⇒ Suitable for applications where signal waveform is important, such as acoustic sensors.
