Research progress in 2D negative Poisson’s ratio material design

Negative Poisson's ratio materials are a class of meta-materials that exhibit unique properties when subjected to external tensile forces. They expand in the direction of the applied force and also undergo anomalous expansion in the direction perpendicular to the force. This characteristic has significant engineering applications, including in damping, cushioning, and bulletproof materials. How...
