- n. The mechanical deformation of a dielectric (insulator) in the presence of an electric field.
from The Century Dictionary and Cyclopedia
- n. Change in the dimensions of, or deformation of, a dielectric produced by the action of an electrostatic field.
Sorry, no etymologies found.
For nonpiezoelectric materials, a higher-order electromechanical coupling gives nonlinear relationship between electrical displacement and strain (e.g., electrostriction), which also can be characterized in terms of constitutive behavior of the material although the intrinsic EM coupling mechanism is less obvious to me.
However since the cap's high-k dielectric's electrostriction signal is in antiphase with the M-E delta mass signal for this test series, the data does take some educated interpretation instead of just a clean yes/no answer to the question of do mass fluctuations exist under the required conditions.
