N2 - A high-frequency ultrasound beamformer based on 70Pb(Mg 1/3Nb2/3)O3-0.30PbTiO3 (PMN-30%PT) single crystal has been designed. The beamformer delays are created using surface acoustic wave (SAW) delay lines, which can be dynamically tuned using the elongation and compression of the bulk PMN-PT substrate between the send and receive SAW electrodes. The change in SAW delay due to the elongation has been measured experimentally and good agreement with the theoretical predictions was found.
