Abstract | Flexible ultrasonic transducers (UTs) consisting of a thin substrate, a piezoelectric ceramic film and electrodes have been developed. The flexibility is realized owing to the porosity of piezoelectric film and the thinness of the substrate and electrodes. In this paper, lead-zirconate-titanate composite piezoelectric film with thickness varying from 40 to 120µm is fabricated by a spray technique. The thin substrates used are stainless steel foils and polyimide films. Electrode materials are silver paste or silver paint. The UT array is configured by the selected top electrodes. The flexible UT array has been successfully tested at 150°C. The array of UT has also been successfully employed as water submerged ultrasonic probe operating in the pulse-echo mode. The UTs have been used for nondestructive testing of different materials with good signal to noise ratio. |
