Described is a touch-sensitive system for sensing one or more touches or objects at a sensing surface. The touch-sensitive system includes an electrode array comprising at least one electrode, the electrode array defining the sensing surface; receiver circuitry configured to couple to the electrode array and receive signals from the electrode array; a controller configured to receive signals from the receiver circuitry and determine a property of a touch or object sensed at the sensing surface; and first drive circuitry configured to generate a first drive signal to be applied to the electrode array. The first drive circuitry is remote from the electrode array and arranged to apply the first drive signal to a user of the touch-sensitive system such that when a user of the touch-sensitive system touches or approaches, directly or via a held object, the sensing surface, the first drive signal is subsequently coupled to the electrode array. The receiver circuitry is configured to receive a signal from the electrode array corresponding to the first drive signal applied to the sensing surface via the user. Also described is a method of operating a touch-sensitive system for sensing one or more touches or objects at a sensing surface.
