    • Negative Poisson's Ratio Behavior Induced by an Elastic Instability 

      Bertoldi, Katia; Reis, Pedro M.; Willshaw, Stephen; Mullin, Tom (Wiley Blackwell, 2010)
      Negative Poisson's ratio behavior has been uncovered in cellular solids that comprise a solid matrix with a square array of circular voids. The simplicity of the fabrication implies robust behavior, which is relevant over ...

    • Switching Periodic Membranes via Pattern Transformation and Shape Memory Effect 

      Li, Jie; Shim, Jongmin; Deng, Justin; Overvelde, Johannes Tesse Bastiaan; Zhu, Xuelian; Bertoldi, Katia; Yang, Shu (The Royal Society of Chemistry, 2012)
      We exploited mechanical instability in shape memory polymer (SMP) membranes consisting of a hexagonal array of micron-sized circular holes and demonstrated dramatic color switching as a result of pattern transformation. ...
