The high driving electric field and the large strain hysteresis are subject to a challenge for piezoelectric actuators’ practical applications. In order to obtain the piezoceramics with giant strain and low hysteresis at small electric field, a ternary solid solution (0.97- x )(K 0.48 Na 0.52 )Nb 0....
