Abstract

High piezoelectric sensitivity and large hydrostatic parameters are discussed for two 1-3-type single crystal/auxetic polymer composites. The single crystal components selected are based on lead-free (K,Na)(Nb,Ta)O₃ and (Li,K,Na)(Nb,Ta)O₃ solid solutions, and the auxetic polymers are characterised by Poisson's ratios -0.83 ≤ v ≤ -0.29. The composites examined exhibit advantageous properties over conventional lead-based piezo-active composites and ceramics such as high longitudinal piezoelectric coefficient g₃₃∗∼(10²-10³) mV · m/N, squared figure of merit (Q₃₃∗)²∼10^-11 Pa^-1, hydrostatic piezoelectric coefficient g_h∗∼(10²-10³) mV · m/N and squared figure of merit (Q_h∗)²∼(10^-11-10^-10) Pa^-1. The composites also demonstrate an infinitely large anisotropy of piezoelectric coefficients d_3j∗.
