Tactile feedback apparatus

摘要

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.

1. A tactile feedback apparatus, comprising:
at least one tactile feedback unit, comprising:
at least one patterned feedback electrode;a dielectric layer, covering the patterned feedback electrode and having a first surface, wherein the first surface has at least one opening; andat least one reference electrode, disposed in the at least one opening of the dielectric layer and exposing at least one surface, wherein the reference electrode is isolated from the patterned feedback electrode by the dielectric layer and the reference electrode corresponding to the first surface is without either overlapping or at least partially overlapping the patterned feedback electrode.
