From: Active-type piezoelectric smart textiles with antifouling performance for pathogenic control
a Experimental and simulation test results for 30% biaxial tensile stretching of the smart textiles. b Simulation results without the fabric. c Simulation results with the fabric incorporated. Impedance and phase angle spectra of the ultrasonic transducers fabricated with d a square-shaped PZT and e a circle-shaped PZT, demonstrating piezoelectricity and the optical image. f Sent pulse signal and g received echo signal by the ultrasonic transducers through an air medium. Displacement of the ultrasonic transducers according to the frequencies and voltages integrated with h square-shaped PZT and (i) circle-shaped PZT.
