Abstract
Piezoelectric bismuth titanate based thick film transducers were deposited onto steel substrates using a sol-gel deposition method. The coated samples were microwave sintered at a temperature of 850 ° C for 10 minutes. Samples had d 33 values in the range of 10-18 pC/N with signal to noise ratios up to 64 dB on a 1.6 cm thick steel block at room temperature. The films tested proved to be capable of ultrasonic wave generation up to and over temperatures of 650 °C.
