Stylus with touch sensor

A stylus may have an elongated body with opposing ends. Electronic equipment may have a touch sensor that receives electromagnetic signals from one or more electrodes. The stylus may have a touch sensor on the elongated body. The touch sensor on the body may have electrodes that gather touch input and optional force input when the fingers of a user touch the stylus. The touch input may include touch gestures in which a user's fingers move along the length of the stylus and may include rotational information indicative of how the stylus is being rotated between the user's fingers. The stylus may have a force sensor that monitors how firmly the stylus is being pressed against external surface and may have other input-output devices. The stylus may transition between operating modes based on signals from the force sensor and other input-output devices in the stylus.
