Abstract
A stylus for a capacitive touch sensor device includes a tip unit, a signal amplification unit and a body unit. The tip unit generates a sensing signal under influence of an electric field. The signal amplification unit is electrically connected to the tip unit and generates an amplified signal by amplifying the sensing signal. The body unit includes a feedback component electrically connected to the signal amplification unit, and an insulation component disposed between the feedback component and the tip unit. The feedback component is made of conducting material and disposed adjacent to the tip unit, so that an electric field resulting from the amplified signal received by the feedback component is fed back to the tip unit.
