Sol-gel Composite Transducers: a Weight Percent Study Bernhard Tittmann

Applications for non-destructive evaluation (NDE) and structural health monitoring (SHM) in principle can be performed at various temperatures provided the transducer can reliably operate under those conditions. This work presents a weight percent study of PZT-Bismuth Titanate composite transducers fabricated through a sol-gel spray-on method to show how different compositions can be used under different monitoring conditions. The two main sections to this work are the theoretical modeling of a composite transducer and the experimental results which validate the theoretical modeling in a given set of conditions.
