The invention concerns an instrumented bearing, in particular for an electric steering wheel (12), comprising an outer element (1) and an inner element (6) whereof one is mobile relative to the other which is fixed, by means of at least a row of rolling elements (14) arranged between said elements, and by detection (22, 23, 31) of rotational parameters of the rotating element. The invention is characterised in that it further comprises electronic means (34) for processing signals emitted by the detecting means and electronic means (35) for controlling at least an actuator electrically connected to the device, advantageously arranged on a printed circuit plate (33) fixed in rotation.
