摘要： A bistable electroactive polymer transducer is provided for electrically actuated deformation of rigid electroactive polymer members. The polymers have glass transition temperatures (Tg) above ambient conditions and turn into rubbery elastomers above Tg and have high dielectric breakdown strength in the rubbery state. They can be electrically deformed to various rigid shapes with maximum strain greater than 100% and as high as 400%. The actuation is made bistable by cooling below Tg to preserve the deformation. The dielectric actuation mechanism includes a pair of compliant electrodes in contact with a dielectric elastomer which deforms when a voltage bias is applied between the pair of electrodes. In some of the transducers of the present invention, the dielectric elastomer is also a shape memory polymer. The deformations of such bistable electroactive polymers can be repeated rapidly for numerous cycles. The polymer transducers have such advantages as high energy and power densities, quietness, mechanical compliancy (for shock resistance and impedance matching), high efficiency, lightweight, and low cost.
摘要翻译：提供双稳态电活性聚合物换能器用于刚性电活性聚合物构件的电致变形。聚合物具有高于环境条件的玻璃化转变温度（Tg），并变成高于Tg的橡胶状弹性体，并且在橡胶状态下具有高介电击穿强度。它们可以电变形为各种刚性形状，最大应变大于100％，高达400％。通过冷却低于Tg使致动双稳态以保持变形。电介质致动机构包括与电介质弹性体接触的一对柔性电极，当在该对电极之间施加电压偏压时，电介质弹性体变形。在本发明的一些换能器中，介电弹性体也是形状记忆聚合物。这种双稳态电活性聚合物的变形可以快速重复多次。聚合物换能器具有高能量和功率密度，安静性，机械兼容性（用于抗冲击和阻抗匹配），高效率，轻量化和低成本等优点。

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.

摘要： A method for controlling the thermal expansion behaviour of a material comprises the step of incorporating into the material a component including one or more diatomic bridges. The or each diatomic bridge extends between two atoms in the component. The method is characterised in that the or each diatomic bridge has at least one vibrational mode that causes the two atoms on either side of the bridge to be moved together to a similar or greater extent than competing vibrational mode(s) that cause the two atoms on either side of the bridge to be moved apart. The bridge may also be polyatomic. New materials and devices comprising a plurality of such diatomic and polyatomic bridges are also defined.

摘要： The present invention refers to a method for obtaining shape changes, motion and/or force in a material having a twinned structure. According to the method, a sufficiently high external magnetic field applied to the material reorients the twin structure thereby producing motion/force. The operation is possible if the magnetocrystalline anisotropy energy is higher than or comparable to the energy of the reorientation of the twin structure to produce a certain strain.

摘要： Embodiments of a magnetic field sensor of the present disclosure includes magnetoelectric nanowires suspended above a substrate across electrodes without substrate clamping. This results in enhanced magnetoelectric coupling by reducing substrate clamping when compared to layered thin-film architectures. Accordingly, the magnetoelectric nanowires of the magnetic field sensor generate a voltage response in the presence of a magnetic field.
