capacitor
This is the dielectric constant of a perfect vacuum, or the field strength that occurs through spacetime itself. Matter has a very large impact on this, and can support the generation of much stronger fields. The best materials are materials with lots of electric dipoles that will enhance the strength of a field generated within the material.
