Abstract: A touch-sensitive display device (10) is characterized in that it is constituted by a stack of layers (1, 4), an insulating layer (2) comprising recesses (21) for the displacement of blades (12) connected to a touch plate (1) being positioned between the touch plate (1) and a layer (3) comprising pancake coils (31) that can be addressed selectively. By modifying the value of currents sent to the different coils (31), the feel of the touch plate (1) can be modified.

Abstract: A device (1) comprising a tactile interface in the form of a plate (10) comprising an array of elements (25) enabling a surface (10a) of the plate (10) to be modified in a controlled manner, characterised in that the plate (10) is made of a shape memory material, and in that each element (25) is made up of an array of blades (23) solid with the plate (10) by an arm (13) solid monolithically with the plate (10) and the blade, a recess (14) of freedom of blade being present around the blade (23), the blade (23) having a first position at a first temperature and a second position at a second temperature.

Abstract: The system of the present invention includes an actuator having at least two electrodes, an elastomeric dielectric film disposed between the two electrodes, and a frame attached to the elastomeric dielectric film. The frame provides a linear actuation force characteristic over a displacement range. The displacement range is preferably the stroke of the actuator. The displacement range can be about 5 mm and greater. Further, the frame can include a plurality of configurations, for example, at least a rigid members coupled to a flexible member wherein the frame provides an elastic restoring force. In preferred embodiments, the rigid member can be, but is not limited to, curved beams, parallel beams, rods and plates.

Abstract: The present invention is directed to devices and systems used in magnetic imaging environments that include an actuator device having an elastomeric dielectric film with at least two electrodes, and a frame attached to the actuator device. The frame can have a plurality of configurations including, such as, for example, at least two members that can be, but not limited to, curved beams, rods, plates, or parallel beams. These rigid members can be coupled to flexible members such as, for example, links wherein the frame provides an elastic restoring force. The frame preferably provides a linear actuation force characteristic over a displacement range. The linear actuation force characteristic is defined as ±20% and preferably 10% over a displacement range. The actuator further includes a passive element disposed between the flexible members to tune a stiffness characteristic of the actuator. The passive element can be a bi-stable element.
