Abstract :
Temperature and humidity are present in almost all environmental conditions and they exert influences in the transducer performance. This study emphasizes the influences of temperature and humidity in two types of air-coupled piezocomposite. It presents the reliability and bandwidth stability of the transducer under temperature and humidity variations.
