Piezoelectricity of PVDF/PUE, PVDF/PMMA and PVDF/(PMMA+BaTiO/sub 3/) laminates
[1991 Proceedings] 7th International Symposium on Electrets (ISE 7), 1992The author suggests the preparation of piezoelectric laminates using PVDF (polyvinylidene fluoride) polymer film (a), polyester urethane elastomer (PUE) film (b), PMMA (polymethyl methacrylate) film (c), and (PMMA+BaTiO/sub 3/) composite film (d).

Multiferroic materials-able to show a good magnetoelectric effect-have been subjected to increasing research in recent years because of the possibility to combine electric and magnetic properties at the same time in the same material. Two kinds of multiferroic materials exist, single-phase and composite materials.

Quasi-Spherical PVDF Ultrasonic Transducer With Double-Cylindrical PVDF Structure
IEEE Sensors Journal, 2020In this paper, a quasi-spherical PVDF airborne ultrasonic transducer for three-dimensional (3D) ultrasonic location systems is designed and fabricated using two strips of cylindrical PVDF film. The 3D solid model of the transducer was created and the acoustic directivity pattern of the transducer was simulated using the finite-element method and the ...

The exploitation of soft conducting polymer-based actuators suffers from two main shortcomings: their short life cycle and the reproducibility of the fabrication techniques. The short life cycle usually results from the delamination of the components due to stresses at the interface during the actuation. In this work, to achieve strong adhesion to poly(

Three types of contact probes are discussed in this research. The probes investigated were a focussing angle beam probe, a normal incidence probe and an acoustic emission probe. Some characteristics of PVDF foils for probe design are also dealt with. A probe design program was used to calculate two types of probes in order to determine the properties ...
