A powered touch screen input device is perpetually self-powered and free of any mechanical connection to the touch screen itself. The input device includes at least one photovoltaic cell supported thereon and disposed to receive light from the display screen associated with the touch screen device. The photovoltaic cell is connected to the electronic signaling circuit disposed within the input device. The input device comprises a stylus having a proximal tip connected to the electronic signaling circuit to generate or receive actinic radiation and interact with the touch screen device. A bezel extends about the barrel to enclose the photovoltaic cells and direct light from the display screen to the cells. Alternatively, RF energy may be transmitted to an antenna in the input device and rectified to drive the electronic signaling circuit.
