Precision-controlled　systems　necessitate　electronic　actuators　with　large　displacement,　high　precision,　and　miniaturization.　Therefore,　advanced　ferroelectric　functional　ceramic　materials　must　exhibit　substantial　displacement　responsiveness,　minimal　hysteresis,　and　performance　stability.　Modifying　electrostrictive　ceramics　to　enhance　the　electrostrictive　coefficient　(Q(33))　through　conventional　doping　strategies　has　proven　challenging.　To　address　this,　grain-oriented　textured　ceramics　harness　crystalline　anisotropy　to　elevate　Q(33)　and　electrostrictive　strain　response.　In　this　work,　we　employ　the　template　grain　growth　(TGG)　method　integrating　preprepared　BaTiO3　(BT)　microtemplates,　to　cultivate　＜001＞-oriented　0.5Ba(Zr0.2Ti0.8)O-3-0.5(Ba0.7Ca0.3)TiO3　(BCZT)　ceramics.　Remarkably,　the　＜001＞-oriented　BCZT　ceramic　manifests　a　substantial　Q(33)　value　of　0.066　m(4)/C-2,　marking　a　65　%　increase　compared　to　randomly　oriented　ceramics.　Under　100　kV/cm,　ultra-high　electrostrictive　strain　response　(0.23%)　and　minimal　hysteresis　(1-8%)　were　achieved.　Crucially,　this　elevated　Q(33)　remains　thermally　stable　within　the　range　of　20-100　degrees　C.　This　advancement　not　only　enables　the　production　of　electrostrictive　ceramics　with　improved　Q(33)　and　hysteresis-free　strain　but　also　broadens　the　application　horizon　of　BCZT-based　electrostrictive　ceramics　within　high-precision　actuator　technologies.
