Abstract
A tactile feedback apparatus is disclosed. The tactile feedback apparatus includes at least one tactile feedback unit. The feedback tactile sense unit includes at least one feedback electrode, a dielectric layer and at least one reference electrode. A common reference potential is formed by a user's finger and the tactile feedback apparatus using the reference electrode. An electric filed is generated on the user's finger by the dielectric layer and the feedback electrode to provide a tactile feedback. Besides, the tactile feedback apparatus also provides a touch sensing function.
