    • A multi-layer piezoelectric actuator with conductive polymer electrodes is described. The piezoelectric actuator comprises a stack of alternating conductive electrode layers and piezoelectric layers. The conductive electrode layers are comprised of a polymeric electrically conductive material. A device for cooling by forced-air convection may comprise the piezoelectric actuator, a fan blade and an alternating current supply. The piezoelectric actuator coupled with the fan blade and the alternating current supply, which is provided for vibrating the fan blade. A method of cooling by forced-air convection comprises supplying an alternating current to the piezoelectric actuator, wherein the alternating current has a frequency and causes the fan blade to vibrate with the same frequency.
    • 描述了具有导电聚合物电极的多层压电致动器。 压电致动器包括交替的导电电极层和压电层的堆叠。 导电电极层由聚合物导电材料构成。 用于通过强制空气对流冷却的装置可以包括压电致动器,风扇叶片和交流电源。 与风扇叶片和用于使风扇叶片振动的交流电源相连接的压电致动器。 通过强制空气对流冷却的方法包括向压电致动器提供交流电流,其中交流电具有频率并使风扇叶片以相同的频率振动。
