<p>An active stylus is disclosed. The stylus (200, 700) includes an electrode at a tip (202, 702) of the stylus; and powered circuitry (206, 706) coupled to the electrode and configured for capacitively coupling the electrode with a capacitive touch sensor panel. The powered circuitry can further include drive circuitry (204) configured to output a drive voltage at the electrode and/or sense circuitry (704) configured to sense a voltage received at the electrode.</p>
