Abstract
Provided is an actuator manufactured using a material obtained by mixing a film material featuring stable motion and high speed of response and used for ion conductive polymer actuators with conductive fine particles. According to the present invention, an actuator which is light in weight, produces low operating noise, and can be used safely and stably, and at the same time, produces expansion/contraction motion, and has speed of response comparable to that of a natural muscle can be obtained.
Claims13
A material for an actuator film which is dipped in an electrolyte solution and expands/contracts in accordance with the application of a voltage, said material being imparted with a high electron conductivity by dispersing conductive fine particles in an ion conductive polymer material having a capacity of capturing a negative or positive electrolyte ion ionized in the electrolyte solution by the application of a voltage.
An actuator film which is dipped in an electrolyte solution together with electrodes and expands/contracts by the application of a predetermined voltage between the electrodes, said actuator film comprising a material being imparted with a high electron conductivity by dispersing conductive fine particles in an ion conductive polymer material having a capacity of capturing a negative or positive electrolyte ion ionized in the electrolyte solution by the application of a voltage.
An actuator comprising an actuator film, an electrode disposed opposite to the actuator film, an electrolyte solution in which the actuator film and the electrode are to be dipped, and a voltage supply for applying a predetermined voltage between the actuator film and the counter electrode, said actuator film comprising a material being imparted with a high electron conductivity by dispersing conductive fine particles in an ion conductive polymer material having a capacity of capturing a negative or positive electrolyte ion ionized in the electrolyte solution by the application of a voltage.
