Electrostriction of Polymer Dielectrics with Compliant Electrodes as Means of Actuation.
These atoms separate the adjacent polymer chains sufficiently to enable the electrostriction effect without preventing crystallization.
One possible alternative to the electrostatically actuated compressors studied to date is based on electrostriction.
The generated pressure in the photoacoustic process can be described by the following wave equation, where electrostriction (26) is ignored:
Taylor expansion and interaction diagram, electrostatic Maxwell stresses and quadratic electrostriction
Recently growing attention has been paid to multi-component mixed oxide perovskites of odd crystalline structures and unique physical properties such as an enormous dielectric permittivity and large piezoelectric and electrostriction coefficients in particular.
On the basis of their sound mechanical properties and high dielectric constants, the modified MWNTs/epoxy composites were deemed as candidate materials for high charge-storage capacitors and electrostriction artificial muscles.
Electrostriction, a second-order electromechanical coupling, is a phenomenon that gives a strain proportional to the square of an applied electric field, and is observed in all materials regardless of crystal symmetry.
