1. An electronic device, comprising:
- a surface;
a substrate positioned adjacent to a side of the surface interior to the electronic device;
a first actuator coupled to the substrate opposite to the surface and configured to contract in response to a first input; and
a second actuator coupled to a first side of the first actuator opposite to the substrate and configured to contract in response to a second input;
wherein;
the first actuator comprises;
a first piezoelectric layer;
a first electrode disposed between the first piezoelectric layer and the substrate; and
a second electrode disposed between the first piezoelectric layer and the second actuator;
the second actuator comprises;
a second piezoelectric layer;
a third electrode disposed between the second piezoelectric layer and the first actuator; and
a fourth electrode disposed on a side of the second piezoelectric layer opposite the third electrode;
the first input is received between the first electrode and the second electrode;
the second input is received between the third electrode and the fourth electrode; and
the substrate is configured to bend;
in a first direction in response to the first actuator contracting, thereby causing at least a portion of the surface of the electronic device to bend in the first direction which provides a localized haptic output on the surface; and
in a second direction in response to the second actuator contracting, thereby causing the portion of the surface of the electronic device to bend in the second direction.

Abstract
Disclosed herein are methods and systems for providing haptic output on an electronic device. In some embodiments, the electronic device includes an actuator configured to move in a first direction. The electronic device also includes a substrate coupled to the actuator. When the actuator moves in the first direction, the substrate or a portion of the substrate, by virtue of being coupled to the actuator, moves in a second direction. In some implementations, the movement of the substrate is perpendicular to the movement of the actuator.
