摘要： Actuators and methods utilizing electrical properties of polymer materials. The actuators have a multilayer structure that includes an electroactive polymer layer between and bonded to first and second electrodes so that the polymer layer has a thickness dimension therebetween. The multilayer structure is adapted so that application of an electric potential to the electrodes causes the electroactive polymer layer to expand in at least one dimension thereof transverse to the thickness dimension of the electroactive polymer layer. The actuators can be used in sealing elements to provide a resealing capability once a condition has occurred of a type that may precede a seal failure.

摘要翻译： 使用聚合物材料电性能的致动器和方法。 致动器具有多层结构，其包括在第一和第二电极之间并结合到第一和第二电极之间的电活性聚合物层，使得聚合物层之间具有厚度尺寸。 多层结构适于使得向电极施加电势导致电活性聚合物层在其至少一个维度上横向于电活性聚合物层的厚度尺寸膨胀。 一旦发生可能在密封故障之前的类型的情况，致动器可以用于密封元件中以提供再密封能力。
