A HAPTIC BUTTON SYSTEM USING A LAYER-STRUCTURED ELECTRO-ACTIVE POLYMER

摘要

A haptic button system using the electroactive polymer of a layered structure is provided to offer reverse stimulus such as the feeling of a button and various tactile sensations such as the feeling of materials to a user according to an application which is being executed. A pair of first electrodes come in contact with both sides of the first electroactive polymer layer(310). The second electroactive polymer layer(330) is located at an upper part of the first electroactive polymer layer and consists of two or more electroactive polymer pieces which are separated from each other. An electric circuit applies a voltage to the first and second electrode pairs.
