报告摘要：
Classical mechanics is intrinsically size-independent and as such does not distinguish between structures that are self-similarly scaled from miles to nanometers. In this presentation, I will discuss a specific physical phenomenon (flexoelectricity) that leads to size-effects in electromechanical coupling. I will argue, through computational examples, the tantalizing possibility of creating “apparently piezoelectric” materials without piezoelectric materials—e.g. graphene, emergence of “giant” piezoelectricity at the nanoscale, nanocapacitors for energy storage and a peculiar indentation size-effect in ferroelectrics. I will also briefly discuss the ramifications of flexoelectricity for soft materials and biological membranes.
