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 PVDF film. The 3D ...

This paper investigates a theoretical analysis of electrical transient responses of a bolt-clamped Langevin ultrasonic transducer (BLT) and its verifications based on simulations and experiments ...

While resistance welding uses Joule heating inside an electrically conductive carbon fibre implant, melting the thermoplastic matrix and forming a strong weld, ultrasonic welding uses high frequency ...
