Published the electrical characteristics graph of the piezo sensor (PVDF polymer piezoelectric)!

Piezo film is a polymer piezoelectric and pyroelectric film developed using KF polymer, a vinylidene fluoride resin, by Kureha Corporation. Its features are: 1. Being a polymer film, it is thin, light, and flexible. ⇒ We offer 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). ⇒ This makes it suitable for sensor applications. 3. The acoustic impedance is close to that of water. ⇒ It is suitable for hydrophones and ultrasonic probes. 4. It does not exhibit strong resonance, meaning it has a small Q value, resulting in a wide response frequency range. ⇒ This is suitable for applications such as acoustic sensors where signal waveform is important.
