Abstract
Provided is an ion conducting actuator that easily allows reduction in size and integration thereof, compared to existing one, and gives a large generating force. The columnar ion conducting actuator includes a tubular member serving as a first electrode, an ion-supplying material disposed inside the tubular member, and linear second electrodes disposed inside the tubular member. The ion-supplying material lies between the inner wall of the tubular member and the second electrodes and includes a polymer gel containing positive ions and negative ions. The tubular member contains a plurality of the second electrodes. Either the positive ions or the negative ions contained in the polymer gel move toward the plurality of second electrodes side and the other ions move toward the inner wall side of the tubular member by applying a voltage between the tubular member and the plurality of the second electrodes to elongate the ion conducting actuator.
