1. A method comprising:
- receiving sensor data from one or more sensors in or on a stylus, the stylus comprising one or more electrodes and one or more computer-readable non-transitory storage media embodying logic for wirelessly transmitting signals to a device through a touch sensor of the device;
modulating a carrier signal to communicate the sensor data; and
wirelessly transmitting from the stylus to the device the carrier signal as modulated through the touch sensor of the device, the device being operable to obtain the sensor data by comparing the carrier signal as modulated to the carrier signal.
