Abstract
A haptic device for an electronic device includes an actuation member formed from a shape-memory alloy (SMA) material that changes shape (e.g., expands or contracts) in response to an applied electrical current. In some cases, the haptic devices described herein also include a restoration mechanism that restores the actuation member to its original shape or to a similar shape. The change in the shape of the actuation member and the restoration of the shape of the actuation member may produce a haptic output at the electronic device.
