... Abstract Piezo based transducers are considered smart sensors in contemporary structural health monitoring (SHM) technologies due to their dual functionality of both actuation and sensing. This function can be used to extract structural impedance in the form of electro-mechanical impedance...

... with several highly sensitive, high frequency transducers. If this system were to consist of a single material, a minimum of three sensors are necessary to triangulate the location of the ping source. However, because this testing device consists of several different materials, as many sensors as practical...

... displacement transducers. In order to obtain a mean value of the modulus of deformability in large rock volumes, as well as information about the rock mass heterogeneity, a group of two co-planar contiguous slots is usually opened for each test. The pressures applied by the jacks to the slot walls often induce...
