Abstract: A touchscreen stylus applies to a capacitive touchscreen and comprises a body being hollow and having an accommodating space thereinside, and a coil arranged inside the accommodating space and forming a current loop. The body also has an electric-conduction element at one end thereof, and the electric-conduction element is used to contact the capacitive touchscreen. The current loop induces an electric field in the coil. The touchscreen detects the induced electric filed and works out the coordinates of the point the touchscreen stylus contacts. In the present invention, the current from the touchscreen needn't flow through the user's hand, and the touchscreen stylus makes the touchscreen detect the contact point more accurately. The touchscreen stylus of the present invention overcomes the conventional problems that current has to flow through the hand and that the touchscreen is unable to correctly recognize the instructions from the stylus.
