Following the work by Evans et al. (Nature, 253 (1991) 124) a quarter of a century ago, the term ‘auxetic’ has now become a familiar word used in materials science to describe materials and metamaterial constructs with the anomalous property of becoming wider rather than thinner when uniaxially stretched, i.e. exhibiting a negative Poisson’s ratio. This talk will present some of the recent developments made in this field by looking at mechanisms which may give rise to this anomalous property. It will also look at how auxeticity may be achieved in materials such as graphene, foams, zeolites and various other crystals, tendons, etc.
