Piezofilm sensor, piezoelectric ultrasonic sensor,piezoelectric detector. Introduction Piezoelectric flouropolymer film or piezo film for short, is a pioneering piezoelectric material born in Japan in 1970s. In the technological backing of Tsinghua University, we realized the production in batches of highly qualified piezo film. 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.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 films 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
