Piezoelectric film ultrasound professional transmitters and professional receivers offer unique advantages for air ranging applications. Resonance frequency and vertical beam directivity of the transmitter and receiver can easily be customized by changing the diameter and length of the PVDF professional cylinder. Cylindrical PVDF receivers exhibit very wide horizontal or omni-directional beam directivity and broad band characteristics. These characteristics lend unique solutions in many applications such as two-dimensional positioning, digitizer, object detection, and distance measurement. Piezo film ultrasound transducers also have very low resonance "Q" values. This means that the signal rise and decay times are much shorter than conventional ceramic ultrasound transducers, making Piezo film transducers ideal for positioning applications.
