Herein, we presented a material-architecture-manufacture integrated strategy for piezoelectric metamaterials to simultaneously achieve mechanical protection and self-powered sensing. Specifically, an intercalation heterostructure of silane-modified barium titanate (K-BTO)\/MXene was constructed to improve the interfacial polarization effect, and an innovative electric field\u2013assisted 4D printing technology could effectively induce the in situ poling of K-BTO. Furthermore, the Kagome lattice\u2013inspired metamaterial (k-CAH) exhibited superior specific energy absorption (0.18 joules per gram), resulting from compression-bend-torsion coordination and multidirection coupling mechanisms. The multimode coupling deformation and local strain amplification mechanism, induced by the geometry design, substantially improved output capacities through activating various piezoelectric response modes at low frequency. With the material-architecture-manufacture synergy,\n                    <jats:inline-formula>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" display=\"inline\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:msubsup>\n                            <mml:mi>g<\/mml:mi>\n                            <mml:mn>33<\/mml:mn>\n                            <mml:mtext>eff<\/mml:mtext>\n                          <\/mml:msubsup>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    reached up to 1.712 volt-meters per newton.
