Pulsed actuation avoids failure in dielectric elastomer artificial muscles
International Journal of Smart and Nano Materials, 2014 Dielectric elastomer actuators (DEAs) are a class of artificial muscles capable of large linear strains (well over 100%), and with high energy density, and low cost and weight.

Optical studies of the pre-breakdown mechanism in dielectronic liquids. [PDF]
, 1977 PhDThe work described in this thesis provides an optical study of pre-breakdown events in liquid dielectrics. A small scale rig employing a 50SI test cell with viewing windows, as part of a high voltage co-axial line, enabled short rise time pulses ...

Electrical breakdown in vacuum
Vacuum, 1953 Direct and impulse voltages were applied to an electrode system in a vacuum of the order of 10−5 mm Hg. Of particular interest were the results obtained with a needle-and-sphere system, the breakdown voltage of which was considerably higher than that of a normal sphere-gap with the same electrode spacing, especially when a very fine needle was used ...
