DEVICES AND METHODS FOR ENERGY CONVERSION BASEDON THE GIANT FLEXOELECTRIC EFFECT IN NON-CALAMITIC LIQUID CRYSTALS

摘要

Devices and methods for energy conversion based on the giant flexoelectric effect in non-calamitic liquid crystals. By preparing a substance comprising at least one type of non-calamitic liquid crystal molecules and stabilizing the substance to form a mechanically flexible material, flexible conductive electrodes may be applied to the material to create an electro-mechanical energy conversion device which relies on the giant flexoelectric effect to produce electrical and/or mechanical energy that is usable in such applications as, for example, power sources, energy dissipation, sensors/transducers, and actuators. The ability to directly and accurately measure the giant flexoelectric effect for different types of non-calamitic liquid crystal molecules is important for identifying molecules that may be effective for particular applications.
