A 2-1-2 composite with two single-crystal components is studied for the first time to highlight large hydrostatic piezoelectric coefficients d h * and g h *, figure of merit d h *g h *, and electromechanical coupling factor k h *. Each 2-1-2 composite contains layers of domain-engineered [011]-poled...
