The sonic screwdriver is a multifunctional fictional tool in the Britishscience fiction television programme Doctor Who and its spinoffs, used by the Doctor. Like the TARDIS, it has become one of the icons of the programme, and spin-off media such as The Sarah Jane Adventures and Torchwood have replicated its functions in devices such as the sonic lipstick, sonic blaster, sonic pen, sonic probe and sonic modulator, and the most recent, sonic sunglasses, featured by the Twelfth Doctor. It seems to use sound waves, radiation, wavelengths, frequencies, signals, and electro-magnetism to function.
