Original Abstract

The high sensitivity with wide bandwidth is required for sensor applications in non-destructive testing (NDT). The sensitivity of piezoceramic sensors demands to minimize their noise especially thermal noise, polarisation noise and 1/f noise, which are the main sources of voltage or current fluctuation in this kind of sensors. For simplicity, only the piezoceramic part of sensor was under study. We investigated samples with the same geometry and material. The theoretical and numerical results are compared with experimental results, which were measured on our noise measurement set-up.
