Abstract :
Sol-gel sprayed piezoelectric composite films have been made at the head of a screw as integrated ultrasonic transducer to propagate longitudinal and shear waves simultaneously along the axial direction of the screw up to 150degC. A discontinuity step is also made near the screw end for accurate velocity measurement. Such screws may be used for axial load and temperature measurements.
