Summary:Three-dimensional piezoelectric PZT-air artificial materials, designed using the Optimal Design by Homogenisation method, with a predicted hydrostatic piezoelectric coefficient of 427 pC/N and a hydrophone figure of merit of 29 pm2/N, were realised and measured. The measured hydrostatic piezoelectric coefficient was 329 pC/N and a hydrophone figure of merit was 19 pm2/N. The differences between predicted and observed properties were ascribed to insufficient polarisation, due to the field distribution during poling. 10 refs.
