Consider the following: writing (and reading) ferroelectric memories without applying voltage;1–3 piezoelectric-like transduction without piezoelectric materials;4–6 bone remodeling7 and mammalian hearing;8,9 asymmetric fracture toughness;10 and bulk photovoltaic effects in non-polar materials.11 What do these apparently disparate phenomena have in common? Flexoelectricity.
