There are provided a touchpad using resistive electro-conductive fibers and an input device having the same, which can be used for controlling a personal terminal such as a computer by receiving a user's input using a signal representing a motion of the user detected by the resistive electro-conductive fiber in contact with the user's body part such as a finger, instead of using a separate input device such as a mouse. The touchpad includes a plurality of motion detectors and a signal analyzer. The motion detectors each include a resistive electro-conductive fiber having a resistance value varied according to a change in length caused by contact with a human body part, and a signal generator outputting a signal corresponding to the varied resistance value. The signal analyzer analyzes the signal from each of the motion detectors, and generates a motion signal representing a motion of the human body part in contact with the touchpad.

Provided are an apparatus and method for monitoring a health index using an electroconductive fiber. In the apparatus, a bio signal acquiring unit measures a bio signal using an electroconductive fiber which is worn around a part of a user's body and in which a resistance is varied according to a user's body volume or body temperature. A health index acquiring unit analyzes the bio signal to acquire a health index. A health index notifying unit notifies the health index. Accordingly, the health index can be easily monitored without limitations on the user's behavior.
