Abstract：Metamaterials can break through theperformance boundariesof traditional materials through artificialstructure design，and show uniqueadvantagesinthe fieldsof impactresistance，energyabsorptionand lightweight.Firstly，the definitionofmetamaterialsandtheirclassificationwereintroduced.Secondly，byintegratingbothnon-gradientandgradient designconcepts，thetwo-dimensionalandthre-dimensional negativePoisson'sratiostructuresalong withtheirmechanical properties weresystematicallysortedout.Thestudyspecificallyhighlightedthedefectsandoptimizationdesignmethodsof the traditionalconcave hexagonalhoneycomb structures，thedevelopmentandmechanicalpropertiesof thethre-dimensionalnongradientnegative Poissn's ratio structures，aswellas the design concept and superior mechanical properties of gradient negativePoisson'sratio structures，etc.Finally，theresearch statusof negativePoisson’sratio metamaterialswas summarized，and the posible futureresearch directions of thismaterial were prospected：1）Conduct research on the mechanical propertiesofnegativePoisson’sratiostructures under multi-physicalfieldcouplingconditions；2）Explorethantiimpactmechanismof three-dimensional negativePoissn’sratio structuresunder multiple workingconditions；3）Carryout gradient optimization designof three-dimensional negative Poison’sratio structures；4）Combine withadvanced manufacturing technologies to realize the integrated design and manufacturing from structure to function.
