Description

Ultrasonic transducers for Resonant Ultrasound Spectroscopy (RUS) need to be produced in a variety of sizes and designs in order to optimize the signals, minimize the effect on the object being measured and deal with odd shaped objects, limited access, and different environments. [1] This continuous requirement to build new transducers for different projects led to the construction technique shown in fig. 1. A piezoelectric element, selected according to the frequency range which is to be covered and the size of the sample, is glued to both an inertial backload and a support, usually a metallized kapton (plastic) diaphragm. Electrical connections to the piezoelectric element are also made with thin metallized kapton with a signal connection glued between the piezo element and the backload and a ground connection made via the diaphragm at the front.
