Polyvinylidene fluoride (PVDF), a material with ferroelectric characteristics, is still extremely
topical for the manufacturing of transducers, and different examples, some of which have …

Transition metal chalcogenides (TMC)(MoS 2 and WS 2) in 2D structure were synthesized
by hydrothermal method on carbon felt (CF) electrodes. Here, we investigated the synthesis …

In 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 …

Up to now, low-frequency ultrasonic transducers have been manufactured using different
materials and technologies and have been inspired by the biological world, mainly by the …

In this paper, a truncated conical polyvinylidene fluoride (PVDF) film transducer for air
ultrasound is investigated. The transducer was designed and fabricated using two identical …

For airborne sound navigation and ranging (SONAR) applications, low frequency and
broadband transducers are required for the detection of obstacles with high axial resolution …

In this paper, we present the VibroCap, a mobility aiding hat which is designed to detect
obstacles and alert the visually impaired user. By using low cost PVDF (Polyvinylidene …

In this paper, we propose an acoustic block for widening the bandwidth and modulating
center frequency of airborne transducers to improve the ultrasound imaging or metrology …

This work aims at providing a theoretical description of an ultrasonic emitting transducer,
which consists of a cylindrical Polyvinylidene fluoride (PVDF) membrane coupled to an air …
