摘要：
Using symmetry arguments we discuss the various possible helical structures that can show a longitudinal piezoelectric effect. Due to the recent experimental verification of such an effect in some elastomeric cholesteric liquid crystals, we propose that what is called cholesterics could actually represent different helical structures, which can be more complicated than the conventional (i.e. simple screw) model.
