A system for measuring EEG signals includes a wearable body adapted to be mounted on the scalp, a plurality of electrodes mounted on the wearable body, and optionally a plurality of controllable actuators for applying a force to the electrodes. A controller optionally controls each actuator or each group of actuators to apply a force to at least one electrode. A signal processor receives and processes the signals from the electrodes and optionally sends control signals to a controller based on the processing.
