    摘要： Osmotic energy transfer systems utilize cyclic electro-chemical stimuli to induce an osmotic gradient and corresponding fluid flows across a semi-permeable membrane. The fluid transfers and osmotic flows are converted into mechanical displacements. By cycling or pulsing the electro-chemical stimuli, fluid transfers across the semi-permeable membrane repeatedly alternatingly change direction over time and correspondingly realizing a cycle of reciprocating mechanical displacements.

    摘要： The actuator device according to the present invention comprises an actuator and an AC power supply capable of applying a high-frequency voltage to the actuator. The actuator comprises a flexible tube formed of a polymer, an inner electrode, and an outer electrode. In a cross section perpendicular to a longitudinal direction of the flexible tube, the inner electrode is in contact with at least a part of an inner periphery of the flexible tube. In the cross section, a part of an outer periphery of the flexible tube is coated with the outer electrode. In operation, the AC power supply applies a high-frequency voltage having a frequency of not less than 1 MHz to the actuator to deform the actuator in a direction from the inner electrode toward the outer electrode in the cross section. The AC power supply stops the application of the high-frequency voltage to the actuator to return the actuator to the original position thereof.

    摘要： An apparatus provides tactile stimulus to a human user using a tri-layer actuator comprising: first and second polymer layers which are electronically and ionically conductive and have one or more dimensions which vary in dependence on insertion of ions therein and withdrawal of ions therefrom; and a deformable layer located between the first and second polymer layers to physically separate the first and second polymer layers from one another, the deformable layer electronically insulating and ionically conductive. Application of first and second voltages between the first and second polymer layers creates corresponding first and second distributions of ions within the first and second polymer layers. Changing between application of the first and second voltages causes corresponding deformation of the tri-layer actuator between corresponding first and second shapes, a difference or transition between the first and second shapes detectable by a sense of touch of a human user.
