To measure the flow velocity of a fluid without affecting its motion state, a method was
proposed based on a polyvinylidene fluoride (PVDF) piezoelectric film sensor. A self-made …

The paper presents a study of surface acoustic waves propagation in a damage layer with
finite thickness and residual stress on an orthotropic semi-infinite medium to reveal the …

Impact loads can have major adverse effects on the safety of civil engineering structures,
such as concrete-filled steel tubular (CFST) columns. The study of mechanical behavior and …

In this paper, the principle of surface acoustic wave techniques and their application to the
monitoring of cracks are presented and compared to other classic non-destructive …

Molecularly imprinted templates for L-Tryptophan sensor using hydrophilic poly (vinylidene
