Abstract
In one embodiment, a stylus includes one or more electrodes and one or more computer-readable non-transitory storage media embodying logic for transmitting signals wirelessly to a device through a touch sensor of the device. The stylus also includes inductive-charging components in or on the stylus for charging or powering the stylus with electromagnetic radiation from inductive-charging components in or on the device. The inductive-charging components in or on the stylus may also charge or power the device by transmitting electromagnetic radiation to the inductive-charging components in or on the device.
