Abstract:
A tactile interface includes a plurality of individually controllable drivers positioned about a perimeter of a tensioned elastomeric material. Each driver includes a first electrode, a second electrode, and a piezoelectric material. A top surface of the first electrode is coupled to the tensioned elastomeric material. The piezoelectric material is disposed between a top surface of the second electrode and a bottom surface of the first electrode. Driver circuitry can apply control information to each of the plurality of individually controllable drivers to produce a wave pattern in the tensioned elastomeric material. Some example methods of providing a tactile image on a tactile interface include producing a time-varying potential difference across the top electrode and the bottom electrode of the drivers so that a standing wave pattern can be created in the elastomeric material. The tactile image can be formed by modulating a subset of the plurality of drivers.
