An electrical insulator that can be polarized by an applied electric field.
1What was really important was the sort of condensers made possible by a genuinely good dielectric material.
2A similar improvement is observed for the case when a thin layer of dielectric material is deposited on the samples.
3Dielectric materials, which store energy electrostatically, are ubiquitous in advanced electronics and electric power systems.
4Flexoelectricity is a universal electromechanical coupling effect whereby all dielectric materials polarise in response to strain gradients.
