Mechanical, optical, and electromechanical investigations were performed on a series of induced cholesteric elastomers. These elastomers are swollen with a chiral low molar mass liquid crystal and exhibit a mechanical coupling coefficient U that is of the same order of magnitude as that for nonswollen nematic elastomers.

Material nonlinear piezoelectric coefficients for quartz
Journal of Applied Physics, 1983An electroelastic or polarizing effect can be used to obtain material nonlinear pizoelectric or electroelastic coefficients. It is shown that these material coefficients, obtained from general rotationally invariant nonlinear equations for small field superposed on a bias, differ from those obtained by using the phenomenological expansion of the ...

Evaluation of the property coefficients of piezoelectric polymers
The Journal of the Acoustical Society of America, 1989Analytical models are presented for evaluating the property coefficients of thick-film piezoelectric polymers. In particular, these models facilitate the evaluation of the complex elastic compliance coefficients ŝ1′1′D, ŝ12D, ŝ22D, ŝ33D, and ŝ66D from the measured set of quantities {fm,fl,fn,Al,An}, where fm is the resonance frequency of the test ...
