The invention provides an electro-adhesion device (10) including a base (12) and first (14) and second (16) banks of thin electrically conductive electrodes (18) located apart from each other on a side of the base (12). The electro-adhesion device (10) also includes an insulating cover (20) over the first (14) and second (16) banks so that the outer side of the insulating cover (20) defines an electro-adhesion surface so that, in use, when the electrodes (18) are energised and an object to be attracted is placed adjacent the insulating cover (20), the object is attracted to the insulating cover (20) by a suitably high adhesion force. An outer surface (24) of each of the electrodes (18) has a linear border on one side and a sinusoidal border on an opposite side so that the width of each electrode (18) varies sinusoidally lengthwise along the electrode (18).
