Embodiment Construction

[0038] The electrorheological fluid device and the electronic device of the present invention have structures respectively, whereby the elasticity of the electrorheological fluid contained in the container is changed to change the hardness, tension, texture or shape of the device or device or to move the device or device mechanically .

[0039] First, the electrorheological fluid (abbreviated as ER fluid) used in the present invention is a fluid in which the viscosity of a substance disposed between the electrodes is significantly changed by an electric field applied to the electrodes. More specifically, the fluid is a fluid comprising microparticles (dispersed phase) dispersed in an electrically insulating liquid (dispersion medium), wherein the microparticles have polarized properties and have a diameter of about 0.1 to 100 μm, wherein, when an external electric field When acting on a suspending fluid, a significant increase in the apparent viscosity of the fluid occurs. Fo...

Abstract

An electric viscous fluid device and electronic equipment capable of being applied also to products requiring a portability by realizing flexible hardness and tension also at the portions thereof brought into contact with the human body, the electric viscous fluid device comprising a storage body for storing fluid therein, a pair of electrodes having a flexibility and disposed in the storage body opposedly to each other, and electric viscous fluid sealed in the storage body, disposed across the pair of electrodes, and having elastic characteristics varying according to an electric field across the electrodes, whereby the hardness, tension, manual touch feeling, and shape of the equipment can be electrically controlled by using the electric viscous fluid device for various types of electronic equipment.

Description

technical field [0001] The present invention relates to an electrorheological fluid device comprising an electrorheological fluid having variable elasticity contained in a container, and an electronic device using the same. Background technique [0002] Many products having a predetermined shape and constituent parts of the products use wood, metal, resin, etc. as raw materials, and they are generally configured to maintain a shape once determined in a manufacturing stage. Elastic parts can change shape under the action of external force, except for parts composed of plastic material, and when the external force within the elastic limit is removed, the elastic parts return to their original shape. [0003] An inherently rigid product or part can be changed in shape and other physical properties not only by the mechanical forces described above but also by other means. For example, when a current of a certain value or more flows through the fuse, constituent components of th...
